HAL_StatusTypeDef HAL_HMACEx_SHA224_Start_DMA	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size
	)

Initializes the HASH peripheral in HMAC SHA224 mode then enables DMA to control data transfer.

Parameters:

hhash	pointer to a HASH_HandleTypeDef structure that contains the configuration information for HASH module
pInBuffer	Pointer to the input buffer (buffer to be hashed).
Size	Length of the input buffer in bytes. If the Size is not multiple of 64 bytes, the padding is managed by hardware.

Return values:

HAL
