Struct Sdio

pub struct Sdio<P: SdioPeripheral> { /* private fields */ }

A peripheral that uses the SDIO hardware, generic over the particular type of device.

Implementations

impl<P: SdioPeripheral> Sdio<P>

pub fn new<PINS: Pins>(sdio: SDIO, pins: PINS, clocks: &Clocks) -> Self

Create and enable the Sdio device

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

Get a reference to the initialized card

pub fn read_block( &mut self, blockaddr: u32, block: &mut [u8; 512], ) -> Result<(), Error>

Read a block from the card

pub fn write_block( &mut self, blockaddr: u32, block: &[u8; 512], ) -> Result<(), Error>

Write a block to card

impl Sdio<SdCard>

pub fn init(&mut self, freq: ClockFreq) -> Result<(), Error>

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

pub fn read_sd_status(&mut self) -> Result<SDStatus, Error>

Read the SDStatus struct

impl Sdio<Emmc>

pub fn init(&mut self, freq: ClockFreq) -> Result<(), Error>

Initializes eMMC device (if present) and sets the bus at the specified frequency. eMMC device must support 512 byte blocks.

pub fn set_bus(&mut self, width: Buswidth, freq: ClockFreq) -> Result<(), Error>
