Functions | |
static uint32_t | CRC_Handle_8 (CRC_HandleTypeDef *hcrc, uint8_t pBuffer[], uint32_t BufferLength) |
Enter 8-bit input data to the CRC calculator. | |
static uint32_t | CRC_Handle_16 (CRC_HandleTypeDef *hcrc, uint16_t pBuffer[], uint32_t BufferLength) |
Enter 16-bit input data to the CRC calculator. | |
HAL_StatusTypeDef | HAL_CRC_Init (CRC_HandleTypeDef *hcrc) |
Initialize the CRC according to the specified parameters in the CRC_InitTypeDef and create the associated handle. | |
HAL_StatusTypeDef | HAL_CRC_DeInit (CRC_HandleTypeDef *hcrc) |
DeInitialize the CRC peripheral. | |
__weak void | HAL_CRC_MspInit (CRC_HandleTypeDef *hcrc) |
Initializes the CRC MSP. | |
__weak void | HAL_CRC_MspDeInit (CRC_HandleTypeDef *hcrc) |
DeInitialize the CRC MSP. | |
uint32_t | HAL_CRC_Accumulate (CRC_HandleTypeDef *hcrc, uint32_t pBuffer[], uint32_t BufferLength) |
Compute the 7, 8, 16 or 32-bit CRC value of an 8, 16 or 32-bit data buffer starting with the previously computed CRC as initialization value. | |
uint32_t | HAL_CRC_Calculate (CRC_HandleTypeDef *hcrc, uint32_t pBuffer[], uint32_t BufferLength) |
Compute the 7, 8, 16 or 32-bit CRC value of an 8, 16 or 32-bit data buffer starting with hcrc->Instance->INIT as initialization value. | |
HAL_CRC_StateTypeDef | HAL_CRC_GetState (CRC_HandleTypeDef *hcrc) |
Return the CRC handle state. |

=============================================================================== ##### How to use this driver ##### =============================================================================== [..] (+) Enable CRC AHB clock using __HAL_RCC_CRC_CLK_ENABLE(); (+) Initialize CRC calculator (++) specify generating polynomial (IP default or non-default one) (++) specify initialization value (IP default or non-default one) (++) specify input data format (++) specify input or output data inversion mode if any (+) Use HAL_CRC_Accumulate() function to compute the CRC value of the input data buffer starting with the previously computed CRC as initialization value (+) Use HAL_CRC_Calculate() function to compute the CRC value of the input data buffer starting with the defined initialization value (default or non-default) to initiate CRC calculation
