DocID028236 Rev 2
uint32_t NumberOfBlocks, uint32_t Timeout)
Function description
Reads block(s) from a specified address in a card.
Parameters
hsd: Pointer to SD handle
pData: pointer to the buffer that will contain the received data
BlockAdd: Block Address from where data is to be read
NumberOfBlocks: Number of SD blocks to read
Timeout: Specify timeout value
Return values
HAL: status
Notes
This API should be followed by a check on the card state
through HAL_SD_GetCardState().
HAL_SD_WriteBlocks
Function name
HAL_StatusTypeDef HAL_SD_WriteBlocks
(SD_HandleTypeDef * hsd, uint8_t * pData, uint32_t BlockAdd,
uint32_t NumberOfBlocks, uint32_t Timeout)
Function description

pData: pointer to the buffer that will contain the data to
transmit
BlockAdd: Block Address where data will be written
NumberOfBlocks: Number of SD blocks to write
Timeout: Specify timeout value
Return values
HAL: status
Notes
This API should be followed by a check on the card state
through HAL_SD_GetCardState().
HAL_SD_Erase
Function name
HAL_StatusTypeDef HAL_SD_Erase (SD_HandleTypeDef *
hsd, uint32_t BlockStartAdd, uint32_t BlockEndAdd)
Function description
