Function Documentation

HAL_SD_ErrorTypedef HAL_SD_Get_CardInfo ( SD_HandleTypeDef *  hsd,
HAL_SD_CardInfoTypedef *  pCardInfo 
)

Returns information about specific card.

Parameters:
hsd,:SD handle
pCardInfo,:Pointer to a HAL_SD_CardInfoTypedef structure that contains all SD cardinformation
Return values:
SDCard error state

< Reserved

Definition at line 1502 of file stm32l4xx_hal_sd.c.

HAL_SD_ErrorTypedef HAL_SD_HighSpeed ( SD_HandleTypeDef *  hsd )

Switches the SD card to High Speed mode.

This API must be used after "Transfer State"

Note:
This operation should be followed by the configuration of PLL to have SDMMCCK clock between 67 and 75 MHz
Parameters:
hsd,:SD handle
Return values:
SDCard error state

Definition at line 1799 of file stm32l4xx_hal_sd.c.

HAL_SD_ErrorTypedef HAL_SD_StopTransfer ( SD_HandleTypeDef *  hsd )

Aborts an ongoing data transfer.

Parameters:
hsd,:SD handle
Return values:
SDCard error state

Definition at line 1772 of file stm32l4xx_hal_sd.c.

HAL_SD_ErrorTypedef HAL_SD_WideBusOperation_Config ( SD_HandleTypeDef *  hsd,
uint32_t  WideMode 
)

Enables wide bus operation for the requested card if supported by card.

Parameters:
hsd,:SD handle
WideMode,:Specifies the SD card wide bus mode This parameter can be one of the following values:

  • SDMMC_BUS_WIDE_8B: 8-bit data transfer (Only for MMC)
  • SDMMC_BUS_WIDE_4B: 4-bit data transfer
  • SDMMC_BUS_WIDE_1B: 1-bit data transfer
Return values:
SDCard error state

Definition at line 1718 of file stm32l4xx_hal_sd.c.
