configWideBusOperation()

static Status::Id imt::base::hal::stm32f769::peripherals::SDMMC::configWideBusOperation ( Handle &  hsd, const BusWidth::Id  wideMode  )

static

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

Parameters

hsd	Pointer to SD handle
wideMode	Specifies the SD card wide bus mode

Return values

HAL

status

HAL_SD_GetCardState()

static CardState::Id imt::base::hal::stm32f769::peripherals::SDMMC::HAL_SD_GetCardState ( Handle &  hsd )

static

Gets the current sd card data state.

Parameters

hsd	pointer to SD handle

Return values

Card

state

init()

static Status::Id imt::base::hal::stm32f769::peripherals::SDMMC::init ( Handle &  hsd )

static

Initializes the SD peripheral according to the specified parameters in the Handle and initiate the associated handle.

Parameters

hsd	Pointer to the SD handle

Return values

HAL

status

readBlocks()

static Status::Id imt::base::hal::stm32f769::peripherals::SDMMC::readBlocks ( Handle &  hsd, uint8_t *const  pData, const uint32_t  blockAdd, const uint32_t  numberOfBlocks, const uint32_t  timeout  )

static

Reads block(s) from a specified address in a card.

The Data transfer is managed by polling mode.

Note

This API should be followed by a check on the card state through HAL_SD_GetCardState().

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

writeBlocks()

static Status::Id imt::base::hal::stm32f769::peripherals::SDMMC::writeBlocks ( Handle &  hsd, const uint8_t *const  pData, const uint32_t  blockAdd, const uint32_t  numberOfBlocks, const uint32_t  timeout  )

static

Allows to write block(s) to a specified address in a card.

The Data transfer is managed by polling mode.

Note

This API should be followed by a check on the card state through HAL_SD_GetCardState().

Parameters

hsd	Pointer to SD handle
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
