Enumerations
enum	{ TRANSFER_WAIT, TRANSFER_COMPLETE, TRANSFER_ERROR }

Functions
static uint8_t	SD_GetCIDRegister (SD_CID *Cid)
	Read the CID card register. Reading the contents of the CID register in SPI mode is a simple read-block transaction. More...
static uint8_t	SD_GetCSDRegister (SD_CSD *Csd)
	Read the CSD card register. Reading the contents of the CSD register in SPI mode is a simple read-block transaction. More...
static SD_Info	SD_GetDataResponse (void)
	Get SD card data response. More...
static uint8_t	SD_GoIdleState (void)
	Put SD in Idle state. More...
static uint8_t	SD_SendCmd (uint8_t Cmd, uint32_t Arg, uint8_t Crc, uint8_t Response)
	Send 5 bytes command to the SD card and get response. More...
static uint8_t	SD_SendCmd_wResp (uint8_t Cmd, uint32_t Arg, uint8_t Crc)
	Send 5 bytes command to the SD card and get response. More...
uint8_t	BSP_SD_Init (void)
	Initialize the SD card. More...
uint8_t	BSP_SD_GetCardInfo (SD_CardInfo *pCardInfo)
	Returns information about specific card. More...
uint8_t	BSP_SD_ReadBlocks (uint32_t *p32Data, uint64_t Sector, uint16_t BlockSize, uint32_t NumberOfBlocks)
	Reads block(s) from a specified address in an SD card, in polling mode. More...
uint8_t	BSP_SD_WriteBlocks (uint32_t *p32Data, uint64_t Sector, uint16_t BlockSize, uint32_t NumberOfBlocks)
	Writes block(s) to a specified address in an SD card, in polling mode. More...
void	HAL_SPI_TxCpltCallback (SPI_HandleTypeDef *hspi)
	TxRx Transfer completed callback. More...
uint8_t	BSP_SD_GetStatus (void)
	Returns the SD status. More...
uint8_t	BSP_SD_Erase (uint32_t StartAddr, uint32_t EndAddr)
	Erases the specified memory area of the given SD card. More...

Variables
__IO uint8_t	SdStatus = SD_PRESENT
__IO uint8_t	SD_CardType = STD_CAPACITY_SD_CARD_V1_1
__IO uint32_t	wTransferState = TRANSFER_WAIT
