This I2C driver provides three different ways for I2C state monitoring
|
||||
depending on the application requirements and constraints:
|
||||
|
||||
|
||||
1. Basic state monitoring (Using I2C_CheckEvent() function)
|
||||
-----------------------------------------------------------
|
||||
It compares the status registers (SR1 and SR2) content to a given event
|
||||
(can be the combination of one or more flags).
|
||||
It returns SUCCESS if the current status includes the given flags
|
||||
and returns ERROR if one or more flags are missing in the current status.
|
||||
|
||||
- When to use
|
||||
- This function is suitable for most applications as well as for startup
|
||||
activity since the events are fully described in the product reference
|
||||
manual (RM0090).
|
||||
- It is also suitable for users who need to define their own events.
|
||||
|
||||
- Limitations
|
||||
- If an error occurs (ie. error flags are set besides to the monitored
|
||||
flags), the I2C_CheckEvent() function may return SUCCESS despite
|
||||
the communication hold or corrupted real state.
|
||||
In this case, it is advised to use error interrupts to monitor
|
||||
the error events and handle them in the interrupt IRQ handler.
|
||||
|
||||
Note
|
||||
For error management, it is advised to use the following functions:
|
||||
- I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
|
||||
- I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
|
||||
Where x is the peripheral instance (I2C1, I2C2 ...)
|
||||
- I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the
|
||||
I2Cx_ER_IRQHandler() function in order to determine which error occurred.
|
||||
- I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
|
||||
and/or I2C_GenerateStop() in order to clear the error flag and source
|
||||
and return to correct communication status.
|
||||
|
||||
|
||||
2. Advanced state monitoring (Using the function I2C_GetLastEvent())
|
||||
--------------------------------------------------------------------
|
||||
Using the function I2C_GetLastEvent() which returns the image of both status
|
||||
registers in a single word (uint32_t) (Status Register 2 value is shifted left
|
||||
by 16 bits and concatenated to Status Register 1).
|
||||
|
||||
- When to use
|
||||
- This function is suitable for the same applications above but it
|
||||
allows to overcome the mentioned limitation of I2C_GetFlagStatus()
|
||||
function.
|
||||
- The returned value could be compared to events already defined in
|
||||
this file or to custom values defined by user.
|
||||
This function is suitable when multiple flags are monitored at the
|
||||
same time.
|
||||
- At the opposite of I2C_CheckEvent() function, this function allows
|
||||
user to choose when an event is accepted (when all events flags are
|
||||
set and no other flags are set or just when the needed flags are set
|
||||
like I2C_CheckEvent() function.
|
||||
|
||||
- Limitations
|
||||
- User may need to define his own events.
|
||||
- Same remark concerning the error management is applicable for this
|
||||
function if user decides to check only regular communication flags
|
||||
(and ignores error flags).
|
||||
|
||||
|
||||
3. Flag-based state monitoring (Using the function I2C_GetFlagStatus())
|
||||
-----------------------------------------------------------------------
|
||||
|
||||
Using the function I2C_GetFlagStatus() which simply returns the status of
|
||||
one single flag (ie. I2C_FLAG_RXNE ...).
|
||||
|
||||
- When to use
|
||||
- This function could be used for specific applications or in debug
|
||||
phase.
|
||||
- It is suitable when only one flag checking is needed (most I2C
|
||||
events are monitored through multiple flags).
|
||||
- Limitations:
|
||||
- When calling this function, the Status register is accessed.
|
||||
Some flags are cleared when the status register is accessed.
|
||||
So checking the status of one Flag, may clear other ones.
|
||||
- Function may need to be called twice or more in order to monitor
|
||||
one single event.

* How to configure Interrupts using driver
|

* ===================================================================
|
||||
*
|
||||
* This section provide functions allowing to configure the NVIC interrupts (IRQ).
|
||||
* The Cortex-M4 exceptions are managed by CMSIS functions.
|
||||
*
|
||||
* 1. Configure the NVIC Priority Grouping using NVIC_PriorityGroupConfig()
|
||||
* function according to the following table.
|
||||
|
||||
* The table below gives the allowed values of the pre-emption priority and subpriority according
|
||||
* to the Priority Grouping configuration performed by NVIC_PriorityGroupConfig function
|
||||
* ==========================================================================================================================
|
||||
* NVIC_PriorityGroup | NVIC_IRQChannelPreemptionPriority | NVIC_IRQChannelSubPriority | Description
|
||||
* ==========================================================================================================================
|
||||
* NVIC_PriorityGroup_0 | 0 | 0-15 | 0 bits for pre-emption priority
|
||||
* | | | 4 bits for subpriority
|
||||
* --------------------------------------------------------------------------------------------------------------------------
|
||||
* NVIC_PriorityGroup_1 | 0-1 | 0-7 | 1 bits for pre-emption priority
|
||||
* | | | 3 bits for subpriority
|
||||
* --------------------------------------------------------------------------------------------------------------------------
|
||||
* NVIC_PriorityGroup_2 | 0-3 | 0-3 | 2 bits for pre-emption priority
|
||||
* | | | 2 bits for subpriority
|
||||
* --------------------------------------------------------------------------------------------------------------------------
|
||||
* NVIC_PriorityGroup_3 | 0-7 | 0-1 | 3 bits for pre-emption priority
|
||||
* | | | 1 bits for subpriority
|
||||
* --------------------------------------------------------------------------------------------------------------------------
|
||||
* NVIC_PriorityGroup_4 | 0-15 | 0 | 4 bits for pre-emption priority
|
||||
* | | | 0 bits for subpriority
|
||||
* ==========================================================================================================================
|
||||
*
|
||||
* 2. Enable and Configure the priority of the selected IRQ Channels using NVIC_Init()
|
||||
*
|
||||
* @note When the NVIC_PriorityGroup_0 is selected, IRQ pre-emption is no more possible.
|
||||
* The pending IRQ priority will be managed only by the subpriority.
|
||||
*
|
||||
* @note IRQ priority order (sorted by highest to lowest priority):
|
||||
* - Lowest pre-emption priority
|
||||
* - Lowest subpriority
|
||||
* - Lowest hardware priority (IRQ number)

===================================================================
|
||||
##### How to use this driver #####
|
||||
===================================================================
|
||||
[..]
|
||||
(#) Enable the CRYP controller clock using
|
||||
RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_CRYP, ENABLE); function.
|
||||
|
||||
(#) Initialise the CRYP using CRYP_Init(), CRYP_KeyInit() and if needed
|
||||
CRYP_IVInit().
|
||||
|
||||
(#) Flush the IN and OUT FIFOs by using CRYP_FIFOFlush() function.
|
||||
|
||||
(#) Enable the CRYP controller using the CRYP_Cmd() function.
|
||||
|
||||
(#) If using DMA for Data input and output transfer, activate the needed DMA
|
||||
Requests using CRYP_DMACmd() function
|
||||
|
||||
(#) If DMA is not used for data transfer, use CRYP_DataIn() and CRYP_DataOut()
|
||||
functions to enter data to IN FIFO and get result from OUT FIFO.
|
||||
|
||||
(#) To control CRYP events you can use one of the following two methods:
|
||||
(++) Check on CRYP flags using the CRYP_GetFlagStatus() function.
|
||||
(++) Use CRYP interrupts through the function CRYP_ITConfig() at
|
||||
initialization phase and CRYP_GetITStatus() function into interrupt
|
||||
routines in processing phase.
|
||||
|
||||
(#) Save and restore Cryptographic processor context using CRYP_SaveContext()
|
||||
and CRYP_RestoreContext() functions.
|
||||
|
||||
|
||||
*** Procedure to perform an encryption or a decryption ***
|
||||
==========================================================
|
||||
|
||||
*** Initialization ***
|
||||
======================
|
||||
[..]
|
||||
(#) Initialize the peripheral using CRYP_Init(), CRYP_KeyInit() and CRYP_IVInit
|
||||
functions:
|
||||
(++) Configure the key size (128-, 192- or 256-bit, in the AES only)
|
||||
(++) Enter the symmetric key
|
||||
(++) Configure the data type
|
||||
(++) In case of decryption in AES-ECB or AES-CBC, you must prepare
|
||||
the key: configure the key preparation mode. Then Enable the CRYP
|
||||
peripheral using CRYP_Cmd() function: the BUSY flag is set.
|
||||
Wait until BUSY flag is reset : the key is prepared for decryption
|
||||
(++) Configure the algorithm and chaining (the DES/TDES in ECB/CBC, the
|
||||
AES in ECB/CBC/CTR)
|
||||
(++) Configure the direction (encryption/decryption).
|
||||
(++) Write the initialization vectors (in CBC or CTR modes only)
|
||||
|
||||
(#) Flush the IN and OUT FIFOs using the CRYP_FIFOFlush() function
|
||||
|
||||
|
||||
*** Basic Processing mode (polling mode) ***
|
||||
============================================
|
||||
[..]
|
||||
(#) Enable the cryptographic processor using CRYP_Cmd() function.
|
||||
|
||||
(#) Write the first blocks in the input FIFO (2 to 8 words) using
|
||||
CRYP_DataIn() function.
|
||||
|
||||
(#) Repeat the following sequence until the complete message has been
|
||||
processed:
|
||||
|
||||
(++) Wait for flag CRYP_FLAG_OFNE occurs (using CRYP_GetFlagStatus()
|
||||
function), then read the OUT-FIFO using CRYP_DataOut() function
|
||||
(1 block or until the FIFO is empty)
|
||||
|
||||
(++) Wait for flag CRYP_FLAG_IFNF occurs, (using CRYP_GetFlagStatus()
|
||||
function then write the IN FIFO using CRYP_DataIn() function
|
||||
(1 block or until the FIFO is full)
|
||||
|
||||
(#) At the end of the processing, CRYP_FLAG_BUSY flag will be reset and
|
||||
both FIFOs are empty (CRYP_FLAG_IFEM is set and CRYP_FLAG_OFNE is
|
||||
reset). You can disable the peripheral using CRYP_Cmd() function.
|
||||
|
||||
*** Interrupts Processing mode ***
|
||||
==================================
|
||||
[..] In this mode, Processing is done when the data are transferred by the
|
||||
CPU during interrupts.
|
||||
|
||||
(#) Enable the interrupts CRYP_IT_INI and CRYP_IT_OUTI using CRYP_ITConfig()
|
||||
function.
|
||||
|
||||
(#) Enable the cryptographic processor using CRYP_Cmd() function.
|
||||
|
||||
(#) In the CRYP_IT_INI interrupt handler : load the input message into the
|
||||
IN FIFO using CRYP_DataIn() function . You can load 2 or 4 words at a
|
||||
time, or load data until the IN FIFO is full. When the last word of
|
||||
the message has been entered into the IN FIFO, disable the CRYP_IT_INI
|
||||
interrupt (using CRYP_ITConfig() function).
|
||||
|
||||
(#) In the CRYP_IT_OUTI interrupt handler : read the output message from
|
||||
the OUT FIFO using CRYP_DataOut() function. You can read 1 block (2 or
|
||||
4 words) at a time or read data until the FIFO is empty.
|
||||
When the last word has been read, INIM=0, BUSY=0 and both FIFOs are
|
||||
empty (CRYP_FLAG_IFEM is set and CRYP_FLAG_OFNE is reset).
|
||||
You can disable the CRYP_IT_OUTI interrupt (using CRYP_ITConfig()
|
||||
function) and you can disable the peripheral using CRYP_Cmd() function.
|
||||
|
||||
*** DMA Processing mode ***
|
||||
===========================
|
||||
[..] In this mode, Processing is done when the DMA is used to transfer the
|
||||
data from/to the memory.
|
||||
|
||||
(#) Configure the DMA controller to transfer the input data from the
|
||||
memory using DMA_Init() function.
|
||||
The transfer length is the length of the message.
|
||||
As message padding is not managed by the peripheral, the message
|
||||
length must be an entire number of blocks. The data are transferred
|
||||
in burst mode. The burst length is 4 words in the AES and 2 or 4
|
||||
words in the DES/TDES. The DMA should be configured to set an
|
||||
interrupt on transfer completion of the output data to indicate that
|
||||
the processing is finished.
|
||||
Refer to DMA peripheral driver for more details.
|
||||
|
||||
(#) Enable the cryptographic processor using CRYP_Cmd() function.
|
||||
Enable the DMA requests CRYP_DMAReq_DataIN and CRYP_DMAReq_DataOUT
|
||||
using CRYP_DMACmd() function.
|
||||
|
||||
(#) All the transfers and processing are managed by the DMA and the
|
||||
cryptographic processor. The DMA transfer complete interrupt indicates
|
||||
that the processing is complete. Both FIFOs are normally empty and
|
||||
CRYP_FLAG_BUSY flag is reset.

|
||||
enabled with the CRYP enable bit. Consequently, when CRYP is disabled, the
|
||||
INMIS signal is low even if the input FIFO is empty.
|
||||
|
||||
|
||||
|
||||
(#) CRYP_IT_OUTI : The output FIFO service interrupt is asserted when there
|
||||
is one or more (32-bit word) data items in the output FIFO. This interrupt
|
||||
is associated to CRYP_FLAG_OUTRIS flag.
|
||||
|
||||
-@- This interrupt is cleared by reading data from the output FIFO until there
|
||||
is no valid (32-bit) word left (that is, the interrupt follows the state
|

of the OFNE (output FIFO not empty) flag).

*** Managing the CRYP controller events : ***
|
||||
=============================================
|
||||
[..] The user should identify which mode will be used in his application to manage
|
||||
the CRYP controller events: Polling mode or Interrupt mode.
|
||||
|
||||
(#) In the Polling Mode it is advised to use the following functions:
|
||||
(++) CRYP_GetFlagStatus() : to check if flags events occur.
|
||||
|
||||
-@@- The CRYPT flags do not need to be cleared since they are cleared as
|
||||
soon as the associated event are reset.
|
||||
|
||||
|
||||
(#) In the Interrupt Mode it is advised to use the following functions:
|
||||
(++) CRYP_ITConfig() : to enable or disable the interrupt source.
|
||||
(++) CRYP_GetITStatus() : to check if Interrupt occurs.
|
||||
|
||||
-@@- The CRYPT interrupts have no pending bits, the interrupt is cleared as
|
||||
soon as the associated event is reset.

===============================================================================
|

##### DAC Peripheral features #####
|
||||
===============================================================================
|
||||
[..]
|
||||
*** DAC Channels ***
|
||||
====================
|
||||
[..]
|
||||
The device integrates two 12-bit Digital Analog Converters that can
|
||||
be used independently or simultaneously (dual mode):
|
||||
(#) DAC channel1 with DAC_OUT1 (PA4) as output
|
||||
(#) DAC channel2 with DAC_OUT2 (PA5) as output
|
||||
|
||||
*** DAC Triggers ***
|
||||
====================
|
||||
[..]
|
||||
Digital to Analog conversion can be non-triggered using DAC_Trigger_None
|
||||
and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register
|
||||
using DAC_SetChannel1Data() / DAC_SetChannel2Data() functions.
|
||||
[..]
|
||||
Digital to Analog conversion can be triggered by:
|
||||
(#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
|
||||
The used pin (GPIOx_Pin9) must be configured in input mode.
|
||||
|
||||
(#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
|
||||
(DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
|
||||
The timer TRGO event should be selected using TIM_SelectOutputTrigger()
|
||||
|
||||
(#) Software using DAC_Trigger_Software
|
||||
|
||||
*** DAC Buffer mode feature ***
|
||||
===============================
|
||||
[..]
|
||||
Each DAC channel integrates an output buffer that can be used to
|
||||
reduce the output impedance, and to drive external loads directly
|
||||
without having to add an external operational amplifier.
|
||||
To enable, the output buffer use
|
||||
DAC_InitStructure.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
|
||||
[..]
|
||||
(@) Refer to the device datasheet for more details about output
|
||||
impedance value with and without output buffer.
|
||||
|
||||
*** DAC wave generation feature ***
|
||||
===================================
|
||||
[..]
|
||||
Both DAC channels can be used to generate
|
||||
(#) Noise wave using DAC_WaveGeneration_Noise
|
||||
(#) Triangle wave using DAC_WaveGeneration_Triangle
|
||||
|
||||
-@- Wave generation can be disabled using DAC_WaveGeneration_None
|
||||
|
||||
*** DAC data format ***
|
||||
=======================
|
||||
[..]
|
||||
The DAC data format can be:
|
||||
(#) 8-bit right alignment using DAC_Align_8b_R
|
||||
(#) 12-bit left alignment using DAC_Align_12b_L
|
||||
(#) 12-bit right alignment using DAC_Align_12b_R
|
||||
|
||||
*** DAC data value to voltage correspondence ***
|
||||
================================================
|
||||
[..]
|
||||
The analog output voltage on each DAC channel pin is determined
|
||||
by the following equation:
|
||||
DAC_OUTx = VREF+ * DOR / 4095
|
||||
with DOR is the Data Output Register
|
||||
VEF+ is the input voltage reference (refer to the device datasheet)
|
||||
e.g. To set DAC_OUT1 to 0.7V, use
|
||||
DAC_SetChannel1Data(DAC_Align_12b_R, 868);
|
||||
Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
|
||||
|
||||
*** DMA requests ***
|
||||
=====================
|
||||
[..]
|
||||
A DMA1 request can be generated when an external trigger (but not
|
||||
a software trigger) occurs if DMA1 requests are enabled using
|
||||
DAC_DMACmd()
|
||||
[..]
|
||||
DMA1 requests are mapped as following:
|
||||
(#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
|
||||
already configured
|
||||
(#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
|
||||
already configured
|
||||
|
||||
|
||||
##### How to use this driver #####
|
||||
===============================================================================
|
||||
[..]
|
||||
(+) DAC APB clock must be enabled to get write access to DAC
|
||||
registers using
|
||||
RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
|
||||
(+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
|
||||
(+) Configure the DAC channel using DAC_Init() function
|
||||
(+) Enable the DAC channel using DAC_Cmd() function

|

##### How to use this driver #####
|
||||
===============================================================================
|
||||
[..]
|
||||
The sequence below describes how to use this driver to capture image
|
||||
from a camera module connected to the DCMI Interface.
|
||||
This sequence does not take into account the configuration of the
|
||||
camera module, which should be made before to configure and enable
|
||||
the DCMI to capture images.
|
||||
|
||||
(#) Enable the clock for the DCMI and associated GPIOs using the following
|
||||
functions:
|
||||
RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_DCMI, ENABLE);
|
||||
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
|
||||
|
||||
(#) DCMI pins configuration
|
||||
(++) Connect the involved DCMI pins to AF13 using the following function
|
||||
GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_DCMI);
|
||||
(++) Configure these DCMI pins in alternate function mode by calling
|
||||
the function GPIO_Init();
|
||||
|
||||
(#) Declare a DCMI_InitTypeDef structure, for example:
|
||||
DCMI_InitTypeDef DCMI_InitStructure;
|
||||
and fill the DCMI_InitStructure variable with the allowed values
|
||||
of the structure member.
|
||||
|
||||
(#) Initialize the DCMI interface by calling the function
|
||||
DCMI_Init(&DCMI_InitStructure);
|
||||
|
||||
(#) Configure the DMA2_Stream1 channel1 to transfer Data from DCMI DR
|
||||
register to the destination memory buffer.
|
||||
|
||||
(#) Enable DCMI interface using the function
|
||||
DCMI_Cmd(ENABLE);
|
||||
|
||||
(#) Start the image capture using the function
|
||||
DCMI_CaptureCmd(ENABLE);
|
||||
|
||||
(#) At this stage the DCMI interface waits for the first start of frame,
|
||||
then a DMA request is generated continuously/once (depending on the
|
||||
mode used, Continuous/Snapshot) to transfer the received data into
|
||||
the destination memory.
|
||||
|
||||
-@- If you need to capture only a rectangular window from the received
|
||||
image, you have to use the DCMI_CROPConfig() function to configure
|
||||
the coordinates and size of the window to be captured, then enable
|
||||
the Crop feature using DCMI_CROPCmd(ENABLE);
|
||||
In this case, the Crop configuration should be made before to enable
|
||||
and start the DCMI interface.

##### EXTI features #####
|
||||
===================================================================
|
||||
|
||||
[..] External interrupt/event lines are mapped as following:
|
||||
(#) All available GPIO pins are connected to the 16 external
|
||||
interrupt/event lines from EXTI0 to EXTI15.
|
||||
(#) EXTI line 16 is connected to the PVD Output
|
||||
(#) EXTI line 17 is connected to the RTC Alarm event
|
||||
(#) EXTI line 18 is connected to the USB OTG FS Wakeup from suspend event
|
||||
(#) EXTI line 19 is connected to the Ethernet Wakeup event
|
||||
(#) EXTI line 20 is connected to the USB OTG HS (configured in FS) Wakeup event
|
||||
(#) EXTI line 21 is connected to the RTC Tamper and Time Stamp events
|
||||
(#) EXTI line 22 is connected to the RTC Wakeup event
|
||||
|
||||
|
||||
##### How to use this driver #####
|
||||
===================================================================
|
||||
|
||||
[..] In order to use an I/O pin as an external interrupt source, follow steps
|
||||
below:
|
||||
(#) Configure the I/O in input mode using GPIO_Init()
|
||||
(#) Select the input source pin for the EXTI line using SYSCFG_EXTILineConfig()
|
||||
(#) Select the mode(interrupt, event) and configure the trigger
|
||||
selection (Rising, falling or both) using EXTI_Init()
|
||||
(#) Configure NVIC IRQ channel mapped to the EXTI line using NVIC_Init()
|
||||
|
||||
[..]
|
||||
(@) SYSCFG APB clock must be enabled to get write access to SYSCFG_EXTICRx
|
||||
registers using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

##### How to use this driver #####
|

===============================================================================
|
||||
[..]
|
||||
(#) Enable the GPIO AHB clock using the following function
|
||||
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
|
||||
|
||||
(#) Configure the GPIO pin(s) using GPIO_Init()
|
||||
Four possible configuration are available for each pin:
|
||||
(++) Input: Floating, Pull-up, Pull-down.
|
||||
(++) Output: Push-Pull (Pull-up, Pull-down or no Pull)
|
||||
Open Drain (Pull-up, Pull-down or no Pull). In output mode, the speed
|
||||
is configurable: 2 MHz, 25 MHz, 50 MHz or 100 MHz.
|
||||
(++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull) Open
|
||||
Drain (Pull-up, Pull-down or no Pull).
|
||||
(++) Analog: required mode when a pin is to be used as ADC channel or DAC
|
||||
output.
|
||||
|
||||
(#) Peripherals alternate function:
|
||||
(++) For ADC and DAC, configure the desired pin in analog mode using
|
||||
GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN;
|
||||
(+++) For other peripherals (TIM, USART...):
|
||||
(+++) Connect the pin to the desired peripherals' Alternate
|
||||
Function (AF) using GPIO_PinAFConfig() function
|
||||
(+++) Configure the desired pin in alternate function mode using
|
||||
GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
|
||||
(+++) Select the type, pull-up/pull-down and output speed via
|
||||
GPIO_PuPd, GPIO_OType and GPIO_Speed members
|
||||
(+++) Call GPIO_Init() function
|
||||
|
||||
(#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
|
||||
|
||||
(#) To set/reset the level of a pin configured in output mode use
|
||||
GPIO_SetBits()/GPIO_ResetBits()
|
||||
|
||||
(#) During and just after reset, the alternate functions are not
|
||||
active and the GPIO pins are configured in input floating mode (except JTAG
|
||||
pins).
|
||||
|
||||
(#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
|
||||
(PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
|
||||
priority over the GPIO function.
|
||||
|
||||
(#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
|
||||
general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
|
||||
The HSE has priority over the GPIO function.

##### How to use this driver #####

===================================================================
|
||||
|
||||
*** HASH operation : ***
|
||||
========================
|
||||
[..]
|
||||
(#) Enable the HASH controller clock using
|
||||
RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_HASH, ENABLE) function.
|
||||
|
||||
(#) Initialise the HASH using HASH_Init() function.
|
||||
|
||||
(#) Reset the HASH processor core, so that the HASH will be ready
|
||||
to compute he message digest of a new message by using HASH_Reset() function.
|
||||
|
||||
(#) Enable the HASH controller using the HASH_Cmd() function.
|
||||
|
||||
(#) if using DMA for Data input transfer, Activate the DMA Request
|
||||
using HASH_DMACmd() function
|
||||
|
||||
(#) if DMA is not used for data transfer, use HASH_DataIn() function
|
||||
to enter data to IN FIFO.
|
||||
|
||||
|
||||
(#) Configure the Number of valid bits in last word of the message
|
||||
using HASH_SetLastWordValidBitsNbr() function.
|
||||
|
||||
(#) if the message length is not an exact multiple of 512 bits,
|
||||
then the function HASH_StartDigest() must be called to launch the computation
|
||||
of the final digest.
|
||||
|
||||
(#) Once computed, the digest can be read using HASH_GetDigest() function.
|
||||
|
||||
(#) To control HASH events you can use one of the following wo methods:
|
||||
(++) Check on HASH flags using the HASH_GetFlagStatus() function.
|
||||
(++) Use HASH interrupts through the function HASH_ITConfig() at
|
||||
initialization phase and HASH_GetITStatus() function into
|
||||
interrupt routines in hashing phase.
|
||||
After checking on a flag you should clear it using HASH_ClearFlag()
|
||||
function. And after checking on an interrupt event you should
|
||||
clear it using HASH_ClearITPendingBit() function.
|
||||
|
||||
(#) Save and restore hash processor context using
|
||||
HASH_SaveContext() and HASH_RestoreContext() functions.
|
||||
|
||||
|
||||
|
||||
*** HMAC operation : ***
|
||||
========================
|
||||
[..] The HMAC algorithm is used for message authentication, by
|
||||
irreversibly binding the message being processed to a key chosen
|
||||
by the user.
|
||||
For HMAC specifications, refer to "HMAC: keyed-hashing for message
|
||||
authentication, H. Krawczyk, M. Bellare, R. Canetti, February 1997"
|
||||
|
||||
[..] Basically, the HMAC algorithm consists of two nested hash operations:
|
||||
HMAC(message) = Hash[((key | pad) XOR 0x5C) | Hash(((key | pad) XOR 0x36) | message)]
|
||||
where:
|
||||
(+) "pad" is a sequence of zeroes needed to extend the key to the
|
||||
length of the underlying hash function data block (that is
|
||||
512 bits for both the SHA-1 and MD5 hash algorithms)
|
||||
(+) "|" represents the concatenation operator
|
||||
|
||||
|
||||
[..]To compute the HMAC, four different phases are required:
|
||||
(#) Initialise the HASH using HASH_Init() function to do HMAC
|
||||
operation.
|
||||
|
||||
(#) The key (to be used for the inner hash function) is then given to the core.
|
||||
This operation follows the same mechanism as the one used to send the
|
||||
message in the hash operation (that is, by HASH_DataIn() function and,
|
||||
finally, HASH_StartDigest() function.
|
||||
|
||||
(#) Once the last word has been entered and computation has started,
|
||||
the hash processor elaborates the key. It is then ready to accept the message
|
||||
text using the same mechanism as the one used to send the message in the
|
||||
hash operation.
|
||||
|
||||
(#) After the first hash round, the hash processor returns "ready" to indicate
|
||||
that it is ready to receive the key to be used for the outer hash function
|
||||
(normally, this key is the same as the one used for the inner hash function).
|
||||
When the last word of the key is entered and computation starts, the HMAC
|
||||
result is made available using HASH_GetDigest() function.

##### Interrupts and flags management functions #####
|
||||
===============================================================================
|
||||
|
||||
[..] This section provides functions allowing to configure the HASH Interrupts and
|
||||
to get the status and clear flags and Interrupts pending bits.
|
||||
|
||||
[..] The HASH provides 2 Interrupts sources and 5 Flags:
|
||||
|
||||
*** Flags : ***
|
||||
===============
|
||||
[..]
|
||||
(#) HASH_FLAG_DINIS : set when 16 locations are free in the Data IN FIFO
|
||||
which means that a new block (512 bit) can be entered into the input buffer.
|
||||
|
||||
(#) HASH_FLAG_DCIS : set when Digest calculation is complete
|
||||
|
||||
(#) HASH_FLAG_DMAS : set when HASH's DMA interface is enabled (DMAE=1) or
|
||||
a transfer is ongoing. This Flag is cleared only by hardware.
|
||||
|
||||
(#) HASH_FLAG_BUSY : set when The hash core is processing a block of data
|
||||
This Flag is cleared only by hardware.
|
||||
|
||||
(#) HASH_FLAG_DINNE : set when Data IN FIFO is not empty which means that
|
||||
the Data IN FIFO contains at least one word of data. This Flag is cleared
|
||||
only by hardware.
|
||||
|
||||
*** Interrupts : ***
|
||||
====================
|
||||
[..]
|
||||
(#) HASH_IT_DINI : if enabled, this interrupt source is pending when 16
|
||||
locations are free in the Data IN FIFO which means that a new block (512 bit)
|
||||
can be entered into the input buffer. This interrupt source is cleared using
|
||||
HASH_ClearITPendingBit(HASH_IT_DINI) function.
|
||||
|
||||
(#) HASH_IT_DCI : if enabled, this interrupt source is pending when Digest
|
||||
calculation is complete. This interrupt source is cleared using
|
||||
HASH_ClearITPendingBit(HASH_IT_DCI) function.
|
||||
|
||||
*** Managing the HASH controller events : ***
|
||||
=============================================
|
||||
[..] The user should identify which mode will be used in his application to manage
|
||||
the HASH controller events: Polling mode or Interrupt mode.
|
||||
|
||||
(#) In the Polling Mode it is advised to use the following functions:
|
||||
(++) HASH_GetFlagStatus() : to check if flags events occur.
|
||||
(++) HASH_ClearFlag() : to clear the flags events.
|
||||
|
||||
(#) In the Interrupt Mode it is advised to use the following functions:
|
||||
(++) HASH_ITConfig() : to enable or disable the interrupt source.
|
||||
(++) HASH_GetITStatus() : to check if Interrupt occurs.
|
||||
(++) HASH_ClearITPendingBit() : to clear the Interrupt pending Bit
|
||||
(corresponding Flag).

* @date 11-January-2013
|
||||
* @brief This file provides firmware functions to manage the following
|
||||
* functionalities of the Independent watchdog (IWDG) peripheral:
|
||||
* + Prescaler and Counter configuration
|
||||
* + IWDG activation
|
||||
* + Flag management
|

|

@verbatim

===============================================================================
|
||||
##### IWDG features #####
|
||||
===============================================================================
|
||||
[..]
|
||||
The IWDG can be started by either software or hardware (configurable
|
||||
through option byte).
|
||||
|
||||
The IWDG is clocked by its own dedicated low-speed clock (LSI) and
|
||||
thus stays active even if the main clock fails.
|
||||
Once the IWDG is started, the LSI is forced ON and cannot be disabled
|
||||
(LSI cannot be disabled too), and the counter starts counting down from
|
||||
the reset value of 0xFFF. When it reaches the end of count value (0x000)
|
||||
a system reset is generated.
|
||||
The IWDG counter should be reloaded at regular intervals to prevent
|
||||
an MCU reset.
|
||||
|
||||
The IWDG is implemented in the VDD voltage domain that is still functional
|
||||
in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
|
||||
|
||||
IWDGRST flag in RCC_CSR register can be used to inform when a IWDG
|
||||
reset occurs.
|
||||
|
||||
Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
|
||||
The IWDG timeout may vary due to LSI frequency dispersion. STM32F4xx
|
||||
devices provide the capability to measure the LSI frequency (LSI clock
|
||||
connected internally to TIM5 CH4 input capture). The measured value
|
||||
can be used to have an IWDG timeout with an acceptable accuracy.
|
||||
For more information, please refer to the STM32F4xx Reference manual
|
||||
|
||||
##### How to use this driver #####
|
||||
===============================================================================
|
||||
[..]
|
||||
(#) Enable write access to IWDG_PR and IWDG_RLR registers using
|
||||
IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function
|
||||
|
||||
(#) Configure the IWDG prescaler using IWDG_SetPrescaler() function
|
||||
|
||||
(#) Configure the IWDG counter value using IWDG_SetReload() function.
|
||||
This value will be loaded in the IWDG counter each time the counter
|
||||
is reloaded, then the IWDG will start counting down from this value.
|
||||
|
||||
(#) Start the IWDG using IWDG_Enable() function, when the IWDG is used
|
||||
in software mode (no need to enable the LSI, it will be enabled
|
||||
by hardware)
|
||||
|
||||
(#) Then the application program must reload the IWDG counter at regular
|
||||
intervals during normal operation to prevent an MCU reset, using
|
||||
IWDG_ReloadCounter() function.

(+) The backup domain includes 4 Kbytes of backup SRAM accessible only from

the CPU, and address in 32-bit, 16-bit or 8-bit mode. Its content is
|
||||
retained even in Standby or VBAT mode when the low power backup regulator
|
||||
is enabled. It can be considered as an internal EEPROM when VBAT is
|
||||
always present. You can use the PWR_BackupRegulatorCmd() function to
|
||||
enable the low power backup regulator and use the PWR_GetFlagStatus
|
||||
(PWR_FLAG_BRR) to check if it is ready or not.
|
||||
|
||||
(+) When the backup domain is supplied by VDD (analog switch connected to VDD)
|
||||
the backup SRAM is powered from VDD which replaces the VBAT power supply to
|
||||
save battery life.
|
||||
|
||||
(+) The backup SRAM is not mass erased by an tamper event. It is read
|
||||
protected to prevent confidential data, such as cryptographic private
|
||||
key, from being accessed. The backup SRAM can be erased only through
|
||||
the Flash interface when a protection level change from level 1 to

level 0 is requested.

-@- Refer to the description of Read protection (RDP) in the Flash

programming manual.

(+) The main internal regulator can be configured to have a tradeoff between
|
||||
performance and power consumption when the device does not operate at
|

the maximum frequency. This is done through PWR_MainRegulatorModeConfig()
|
||||

===============================================================================
|

##### Low Power modes configuration functions #####
|
||||
===============================================================================
|
||||
[..]
|
||||
The devices feature 3 low-power modes:
|
||||
(+) Sleep mode: Cortex-M4 core stopped, peripherals kept running.
|
||||
(+) Stop mode: all clocks are stopped, regulator running, regulator
|
||||
in low power mode
|
||||
(+) Standby mode: 1.2V domain powered off.
|
||||
|
||||
*** Sleep mode ***
|
||||
==================
|
||||
[..]
|
||||
(+) Entry:
|
||||
(++) The Sleep mode is entered by using the __WFI() or __WFE() functions.
|
||||
(+) Exit:
|
||||
(++) Any peripheral interrupt acknowledged by the nested vectored interrupt
|
||||
controller (NVIC) can wake up the device from Sleep mode.
|
||||
|
||||
*** Stop mode ***
|
||||
=================
|
||||
[..]
|
||||
In Stop mode, all clocks in the 1.2V domain are stopped, the PLL, the HSI,
|
||||
and the HSE RC oscillators are disabled. Internal SRAM and register contents
|
||||
are preserved.
|
||||
The voltage regulator can be configured either in normal or low-power mode.
|
||||
To minimize the consumption In Stop mode, FLASH can be powered off before
|
||||
entering the Stop mode. It can be switched on again by software after exiting
|
||||
the Stop mode using the PWR_FlashPowerDownCmd() function.
|
||||
|
||||
(+) Entry:
|
||||
(++) The Stop mode is entered using the PWR_EnterSTOPMode(PWR_Regulator_LowPower,)
|
||||
function with regulator in LowPower or with Regulator ON.
|
||||
(+) Exit:
|
||||
(++) Any EXTI Line (Internal or External) configured in Interrupt/Event mode.
|
||||
|
||||
*** Standby mode ***
|
||||
====================
|
||||
[..]
|
||||
The Standby mode allows to achieve the lowest power consumption. It is based
|
||||
on the Cortex-M4 deepsleep mode, with the voltage regulator disabled.
|
||||
The 1.2V domain is consequently powered off. The PLL, the HSI oscillator and
|
||||
the HSE oscillator are also switched off. SRAM and register contents are lost
|
||||
except for the RTC registers, RTC backup registers, backup SRAM and Standby
|
||||
circuitry.
|
||||
|
||||
The voltage regulator is OFF.
|
||||
|
||||
(+) Entry:
|
||||
(++) The Standby mode is entered using the PWR_EnterSTANDBYMode() function.
|
||||
(+) Exit:
|
||||
(++) WKUP pin rising edge, RTC alarm (Alarm A and Alarm B), RTC wakeup,
|
||||
tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
|
||||
|
||||
*** Auto-wakeup (AWU) from low-power mode ***
|
||||
=============================================
|
||||
[..]
|
||||
The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC
|
||||
Wakeup event, a tamper event, a time-stamp event, or a comparator event,
|
||||
without depending on an external interrupt (Auto-wakeup mode).
|
||||
|
||||
(#) RTC auto-wakeup (AWU) from the Stop mode
|
||||
|
||||
(++) To wake up from the Stop mode with an RTC alarm event, it is necessary to:
|
||||
(+++) Configure the EXTI Line 17 to be sensitive to rising edges (Interrupt
|
||||
or Event modes) using the EXTI_Init() function.
|
||||
(+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function
|
||||
(+++) Configure the RTC to generate the RTC alarm using the RTC_SetAlarm()
|
||||
and RTC_AlarmCmd() functions.
|
||||
(++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it
|
||||
is necessary to:
|
||||
(+++) Configure the EXTI Line 21 to be sensitive to rising edges (Interrupt
|
||||
or Event modes) using the EXTI_Init() function.
|
||||
(+++) Enable the RTC Tamper or time stamp Interrupt using the RTC_ITConfig()
|
||||
function
|
||||
(+++) Configure the RTC to detect the tamper or time stamp event using the
|
||||
RTC_TimeStampConfig(), RTC_TamperTriggerConfig() and RTC_TamperCmd()
|
||||
functions.
|
||||
(++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to:
|
||||
(+++) Configure the EXTI Line 22 to be sensitive to rising edges (Interrupt
|
||||
or Event modes) using the EXTI_Init() function.
|
||||
(+++) Enable the RTC WakeUp Interrupt using the RTC_ITConfig() function
|
||||
(+++) Configure the RTC to generate the RTC WakeUp event using the RTC_WakeUpClockConfig(),
|
||||
RTC_SetWakeUpCounter() and RTC_WakeUpCmd() functions.
|
||||
|
||||
(#) RTC auto-wakeup (AWU) from the Standby mode
|
||||
|
||||
(++) To wake up from the Standby mode with an RTC alarm event, it is necessary to:
|
||||
(+++) Enable the RTC Alarm Interrupt using the RTC_ITConfig() function

===============================================================================
|
||||
##### Interrupts and flags management functions #####
|
||||
===============================================================================
|
||||
|
||||
[..] This section provides functions allowing to configure the RNG Interrupts and
|
||||
to get the status and clear flags and Interrupts pending bits.
|
||||
|
||||
[..] The RNG provides 3 Interrupts sources and 3 Flags:
|
||||
|
||||
*** Flags : ***
|
||||
===============
|
||||
[..]
|
||||
(#) RNG_FLAG_DRDY : In the case of the RNG_DR register contains valid
|
||||
random data. it is cleared by reading the valid data(using
|
||||
RNG_GetRandomNumber() function).
|
||||
|
||||
(#) RNG_FLAG_CECS : In the case of a seed error detection.
|
||||
|
||||
(#) RNG_FLAG_SECS : In the case of a clock error detection.
|
||||
|
||||
*** Interrupts ***
|
||||
==================
|
||||
[..] If enabled, an RNG interrupt is pending :
|
||||
|
||||
(#) In the case of the RNG_DR register contains valid random data.
|
||||
This interrupt source is cleared once the RNG_DR register has been read
|
||||
(using RNG_GetRandomNumber() function) until a new valid value is
|
||||
computed; or
|
||||
(#) In the case of a seed error : One of the following faulty sequences has
|
||||
been detected:
|
||||
(++) More than 64 consecutive bits at the same value (0 or 1)
|
||||
(++) More than 32 consecutive alternance of 0 and 1 (0101010101...01)
|
||||
This interrupt source is cleared using RNG_ClearITPendingBit(RNG_IT_SEI)
|
||||
function; or
|
||||
(#) In the case of a clock error : the PLL48CLK (RNG peripheral clock source)
|
||||
was not correctly detected (fPLL48CLK< fHCLK/16). This interrupt source is
|
||||
cleared using RNG_ClearITPendingBit(RNG_IT_CEI) function.
|
||||
-@- note In this case, User have to check that the clock controller is
|
||||
correctly configured to provide the RNG clock.
|
||||
|
||||
*** Managing the RNG controller events : ***
|
||||
============================================
|
||||
[..] The user should identify which mode will be used in his application to manage
|
||||
the RNG controller events: Polling mode or Interrupt mode.
|
||||
|
||||
(#) In the Polling Mode it is advised to use the following functions:
|
||||
(++) RNG_GetFlagStatus() : to check if flags events occur.
|
||||
(++) RNG_ClearFlag() : to clear the flags events.
|
||||
|
||||
-@@- RNG_FLAG_DRDY can not be cleared by RNG_ClearFlag(). it is cleared only
|
||||
by reading the Random number data.
|
||||
|
||||
(#) In the Interrupt Mode it is advised to use the following functions:
|
||||
(++) RNG_ITConfig() : to enable or disable the interrupt source.
|
||||
(++) RNG_GetITStatus() : to check if Interrupt occurs.
|
||||
(++) RNG_ClearITPendingBit() : to clear the Interrupt pending Bit
|
||||
(corresponding Flag).

##### WWDG features #####
|
||||
===============================================================================
|
||||
[..]
|
||||
Once enabled the WWDG generates a system reset on expiry of a programmed
|
||||
time period, unless the program refreshes the counter (downcounter)
|
||||
before to reach 0x3F value (i.e. a reset is generated when the counter
|
||||
value rolls over from 0x40 to 0x3F).
|
||||
An MCU reset is also generated if the counter value is refreshed
|
||||
before the counter has reached the refresh window value. This
|
||||
implies that the counter must be refreshed in a limited window.
|
||||
|
||||
Once enabled the WWDG cannot be disabled except by a system reset.
|
||||
|
||||
WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
|
||||
reset occurs.
|
||||
|
||||
The WWDG counter input clock is derived from the APB clock divided
|
||||
by a programmable prescaler.
|
||||
|
||||
WWDG counter clock = PCLK1 / Prescaler
|
||||
WWDG timeout = (WWDG counter clock) * (counter value)
|
||||
|
||||
Min-max timeout value @42 MHz(PCLK1): ~97.5 us / ~49.9 ms
|
||||
|
||||
##### How to use this driver #####
|
||||
===============================================================================
|
||||
[..]
|
||||
(#) Enable WWDG clock using RCC_APB1PeriphClockCmd(RCC_APB1Periph_WWDG, ENABLE) function
|
||||
|
||||
(#) Configure the WWDG prescaler using WWDG_SetPrescaler() function
|
||||
|
||||
(#) Configure the WWDG refresh window using WWDG_SetWindowValue() function
|
||||
|
||||
(#) Set the WWDG counter value and start it using WWDG_Enable() function.
|
||||
When the WWDG is enabled the counter value should be configured to
|
||||
a value greater than 0x40 to prevent generating an immediate reset.
|
||||
|
||||
(#) Optionally you can enable the Early wakeup interrupt which is
|
||||
generated when the counter reach 0x40.
|
||||
Once enabled this interrupt cannot be disabled except by a system reset.
|
||||
|
||||
(#) Then the application program must refresh the WWDG counter at regular
|
||||
intervals during normal operation to prevent an MCU reset, using
|
||||
WWDG_SetCounter() function. This operation must occur only when
|
||||
the counter value is lower than the refresh window value,
|
||||
programmed using WWDG_SetWindowValue().

* @date 24-May-2013
|
||||
* @brief CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
|
||||
* This file contains the system clock configuration for STM32F4xx devices,
|
||||
* and is generated by the clock configuration tool
|
||||
* stm32f4xx_Clock_Configuration_V1.1.0.xls
|
||||
*
|
||||
* 1. This file provides two functions and one global variable to be called from
|
||||
* user application:
|
||||
* - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
|
||||
* and Divider factors, AHB/APBx prescalers and Flash settings),
|
||||
* depending on the configuration made in the clock xls tool.
|
||||
* This function is called at startup just after reset and
|
||||
* before branch to main program. This call is made inside
|
||||
* the "startup_stm32f4xx.s" file.
|
||||
*
|
||||
* - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
|
||||
* by the user application to setup the SysTick
|
||||
* timer or configure other parameters.
|
||||
*
|
||||
* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
|
||||
* be called whenever the core clock is changed
|
||||
* during program execution.
|
||||
*
|
||||
* 2. After each device reset the HSI (16 MHz) is used as system clock source.
|
||||
* Then SystemInit() function is called, in "startup_stm32f4xx.s" file, to
|
||||
* configure the system clock before to branch to main program.
|
||||
*
|
||||
* 3. If the system clock source selected by user fails to startup, the SystemInit()
|
||||
* function will do nothing and HSI still used as system clock source. User can
|
||||
* add some code to deal with this issue inside the SetSysClock() function.
|
||||
*
|
||||
* 4. The default value of HSE crystal is set to 25MHz, refer to "HSE_VALUE" define
|
||||
* in "stm32f4xx.h" file. When HSE is used as system clock source, directly or
|
||||
* through PLL, and you are using different crystal you have to adapt the HSE
|
||||
* value to your own configuration.
|
||||
*
|
||||
* 5. This file configures the system clock as follows:

*
|

* @note - The system frequency computed by this function is not the real

* constant and the selected clock source:
|

*
|

* - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**)
|
||||
* or HSI_VALUE(*) multiplied/divided by the PLL factors.
|
||||
*
|
||||
* (*) HSI_VALUE is a constant defined in stm32f4xx.h file (default value

* in voltage and temperature.
|

* (**) HSE_VALUE is a constant defined in stm32f4xx.h file (default value
