    ==============================================================================
                    ##### Peripheral Control functions #####
    ==============================================================================
      [..]  This section provides functions allowing to:
        (+) Compute the 32-bit CRC value of 32-bit data buffer,
            using combination of the previous CRC value and the new one.
        (+) Compute the 32-bit CRC value of 32-bit data buffer,
            independently of the previous CRC value.

HAL_CRC_Accumulate()

uint32_t HAL_CRC_Accumulate	(	CRC_HandleTypeDef *	hcrc,
		uint8_t *	pBuffer,
		uint32_t	BufferLength
	)

Computes the 32-bit CRC of 32-bit data buffer using combination of the previous CRC value and the new one.

Parameters

hcrc	pointer to a CRC_HandleTypeDef structure that contains the configuration information for CRC
pBuffer	pointer to the buffer containing the data to be computed
BufferLength	length of the buffer to be computed

Return values

32-bit

CRC

HAL_CRC_Calculate()

uint32_t HAL_CRC_Calculate	(	CRC_HandleTypeDef *	hcrc,
		uint8_t *	pBuffer,
		uint32_t	BufferLength

	)

Set Cutomized CRC mode for calculation.

Parameters

hcrc	pointer to a CRC_HandleTypeDef structure that contains the configuration information for CRC
init	initial CRC value
poly	Programmable polynomial
mode	Mode for CRC calculation, but use customized initial value and poly
