impl<'d, T: Instance, Dma: SdmmcDma<T> + 'd> Sdmmc<'d, T, Dma>

pub async fn init_card(&mut self, freq: Hertz) -> Result<(), Error>

Initializes card (if present) and sets the bus at the specified frequency.

pub async fn read_block( &mut self, block_idx: u32, buffer: &mut DataBlock ) -> Result<(), Error>

Read a data block.

pub async fn write_block( &mut self, block_idx: u32, buffer: &DataBlock ) -> Result<(), Error>

Write a data block.

pub fn card(&self) -> Result<&Card, Error>

Get a reference to the initialized card

Errors

Returns Error::NoCard if init_card has not previously succeeded

pub fn clock(&self) -> Hertz

Get the current SDMMC bus clock
