For example, + * the type + * definition for the floating-point matrix structure is shown + * below: + * 
+ *     typedef struct
+ *     {
+ *       uint16_t numRows;     // number of rows of the matrix.
+ *       uint16_t numCols;     // number of columns of the matrix.
+ *       float32_t *pData;     // points to the data of the matrix.
+ *     } arm_matrix_instance_f32;
+ *
+ * There are similar definitions for Q15 and Q31 data types. + * + * The structure specifies the size of the matrix and then points to + * an array of data. The array is of size numRows X numCols + * and the values are arranged in row order. That is, the + * matrix element (i, j) is stored at: + * 
+ *     pData[i*numCols + j]
+ *
+ * + * \par Init Functions + * There is an associated initialization function for each type of matrix + * data structure. + * The initialization function sets the values of the internal structure fields. + * Refer to the function arm_mat_init_f32(), arm_mat_init_q31() + * and arm_mat_init_q15() for floating-point, Q31 and Q15 types, respectively. + * + * \par + * Use of the initialization function is optional. However, if initialization function is used + * then the instance structure cannot be placed into a const data section. + * To place the instance structure in a const data + * section, manually initialize the data structure. For example: + * 
+ * arm_matrix_instance_f32 S = {nRows, nColumns, pData};
+ * arm_matrix_instance_q31 S = {nRows, nColumns, pData};
+ * arm_matrix_instance_q15 S = {nRows, nColumns, pData};
+ *
+ * where nRows specifies the number of rows, nColumns + * specifies the number of columns, and pData points to the + * data array. + * + * \par Size Checking + * By default all of the matrix functions perform size checking on the input and + * output matrices. For example, the matrix addition function verifies that the + * two input matrices and the output matrix all have the same number of rows and + * columns. If the size check fails the functions return: + * 
+ *     ARM_MATH_SIZE_MISMATCH
+ *
+ * Otherwise the functions return + * 
+ *     ARM_MATH_SUCCESS
+ *
+ * There is some overhead associated with this matrix size checking. + * The matrix size checking is enabled via the #define + * 
+ *     ARM_MATH_MATRIX_CHECK
+ *

SPI, USART ...) + The function allowing this operation is provided in each PPP peripheral + driver (ie. SPI_DMACmd for SPI peripheral). + (#) Optionally, you can configure the number of data to be transferred + when the channel is disabled (ie. after each Transfer Complete event + or when a Transfer Error occurs) using the function DMA_SetCurrDataCounter(). + And you can get the number of remaining data to be transferred using + the function DMA_GetCurrDataCounter() at run time (when the DMA channel is + enabled and running). + (#) To control DMA events you can use one of the following two methods: + (##) Check on DMA channel flags using the function DMA_GetFlagStatus(). + (##) Use DMA interrupts through the function DMA_ITConfig() at initialization + phase and DMA_GetITStatus() function into interrupt routines in + communication phase. + After checking on a flag you should clear it using DMA_ClearFlag() + function.

You can use the + RCC_BackupResetCmd(). + (#) VDD or VBAT power on, if both supplies have previously been + powered off. + + ##### Backup Domain Access ##### + =============================================================================== + [..] After reset, the backup domain (RTC registers and RTC backup data + registers) is protected against possible unwanted write accesses. + [..] To enable access to the Backup Domain and RTC registers, proceed as follows: + (#) Enable the Power Controller (PWR) APB1 interface clock using the + RCC_APB1PeriphClockCmd() function. + (#) Enable access to Backup domain using the PWR_BackupAccessCmd() function. + (#) Select the RTC clock source using the RCC_RTCCLKConfig() function. + (#) Enable RTC Clock using the RCC_RTCCLKCmd() function. + + + ##### How to use this driver ##### + =============================================================================== + [..] + (+) Enable the backup domain access (see description in the section above) + (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and + RTC hour format using the RTC_Init() function. + + ***Time and Date configuration *** + ================================== + [..] + (+) To configure the RTC Calendar (Time and Date) use the RTC_SetTime() + and RTC_SetDate() functions. + (+) To read the RTC Calendar, use the RTC_GetTime() and RTC_GetDate() + functions. + (+) To read the RTC subsecond, use the RTC_GetSubSecond() function. + (+) Use the RTC_DayLightSavingConfig() function to add or sub one + hour to the RTC Calendar. + + ***Alarm configuration *** + ========================== + [..] + (+) To configure the RTC Alarm use the RTC_SetAlarm() function. + (+) Enable the selected RTC Alarm using the RTC_AlarmCmd() function + (+) To read the RTC Alarm, use the RTC_GetAlarm() function. + (+) To read the RTC alarm SubSecond, use the RTC_GetAlarmSubSecond() function. + + ***Outputs configuration *** + ============================ + [..] The RTC has 2 different outputs: + (+) AFO_ALARM: this output is used to manage the RTC Alarm A. + To output the selected RTC signal on RTC_AF1 pin, use the + RTC_OutputConfig() function. + (+) AFO_CALIB: this output is 512Hz signal or 1Hz . + To output the RTC Clock on RTC_AF1 pin, use the RTC_CalibOutputCmd() + function. + + ***Original Digital Calibration configuration *** + ================================= + [..] Configure the RTC Original Digital Calibration Value and the corresponding + calibration cycle period (32s,16s and 8s) using the RTC_SmoothCalibConfig() + function. + + ***TimeStamp configuration *** + ============================== + [..] + (+) Configure the RTC_AF1 trigger and enables the RTC TimeStamp + using the RTC_TimeStampCmd() function. + (+) To read the RTC TimeStamp Time and Date register, use the + RTC_GetTimeStamp() function. + (+) To read the RTC TimeStamp SubSecond register, use the + RTC_GetTimeStampSubSecond() function. + + ***Tamper configuration *** + =========================== + [..] + (+) Configure the Tamper filter count using RTC_TamperFilterConfig() + function. + (+) Configure the RTC Tamper trigger Edge or Level according to the Tamper + filter (if equal to 0 Edge else Level) value using the RTC_TamperConfig() function + (+) Configure the Tamper sampling frequency using RTC_TamperSamplingFreqConfig() + function. + (+) Configure the Tamper precharge or discharge duration using + RTC_TamperPinsPrechargeDuration() function. + (+) Enable the Tamper Pull-UP using RTC_TamperPullUpDisableCmd() function. + (+) Enable the RTC Tamper using the RTC_TamperCmd() function. + (+) Enable the Time stamp on Tamper detection event using + RTC_TSOnTamperDetecCmd() function. + + ***Backup Data Registers configuration *** + ========================================== + [..] + (+) To write to the RTC Backup Data registers, use the RTC_WriteBackupRegister() + function. + (+) To read the RTC Backup Data registers, use the RTC_ReadBackupRegister() + function. + + ##### RTC and low power modes ##### + =============================================================================== + [..] The MCU can be woken up from a low power mode by an RTC alternate + function. + [..] The RTC alternate functions are the RTC alarm (Alarm A), RTC tamper + event detection and RTC time stamp event detection. + These RTC alternate functions can wake up the system from the Stop + and Standby lowpower modes. + The system can also wake up from low power modes without depending + on an external interrupt (Auto-wakeup mode), by using the RTC alarm events. + [..] The RTC provides a programmable time base for waking up from the + Stop or Standby mode at regular intervals. + Wakeup from STOP and Standby modes is possible only when the RTC + clock source is LSE or LSI. + + ##### Selection of RTC_AF1 alternate functions ##### + =============================================================================== + [..] The RTC_AF1 pin (PC13) can be used for the following purposes: + (+) AFO_ALARM output + (+)
