 ===============================================================================
    [..]  This section provides functions allowing to:
      (+) compute the 32-bit CRC value of a 32-bit data buffer
          using combination of the previous CRC value and the new one.

       [..]  or

      (+) compute the 32-bit CRC value of a 32-bit data buffer
          independently of the previous CRC value.

◆ HAL_CRC_Accumulate()

uint32_t HAL_CRC_Accumulate	(	CRC_HandleTypeDef *	hcrc,
		uint32_t	pBuffer[],
		uint32_t	BufferLength
	)

Compute the 32-bit CRC value of a 32-bit data buffer starting with the previously computed CRC as initialization value.

Parameters

hcrc	CRC handle
pBuffer	pointer to the input data buffer.
BufferLength	input data buffer length (number of uint32_t words).

Return values

uint32_t CRC (returned value LSBs for CRC shorter than 32 bits)

◆ HAL_CRC_Calculate()

uint32_t HAL_CRC_Calculate	(	CRC_HandleTypeDef *	hcrc,
		uint32_t	pBuffer[],
		uint32_t	BufferLength
	)

Compute the 32-bit CRC value of a 32-bit data buffer starting with hcrc->Instance->INIT as initialization value.
