Struct capsules_extra::sdcard::SDCard

pub struct SDCard<'a, A: Alarm<'a>> { /* private fields */ }

SD Card capsule, capable of being built on top of by other kernel capsules

Implementations

impl<'a, A: Alarm<'a>> SDCard<'a, A>

Functions for initializing and accessing an SD card

pub fn new( spi: &'a dyn SpiMasterDevice<'_>, alarm: &'a A, detect_pin: Option<&'static dyn InterruptPin<'a>>, txbuffer: &'static mut [u8; 515], rxbuffer: &'static mut [u8; 515], ) -> SDCard<'a, A>

Create a new SD card interface

spi - virtualized SPI to use for communication with SD card alarm - virtualized Timer with a granularity of at least 1 ms detect_pin - active low GPIO pin used to detect if an SD card is installed txbuffer - buffer for holding SPI write data, at least 515 bytes in length rxbuffer - buffer for holding SPI read data, at least 515 bytes in length

pub fn set_client<C: SDCardClient>(&self, client: &'static C)

pub fn is_installed(&self) -> bool

pub fn is_initialized(&self) -> bool

pub fn detect_changes(&self)

watches SD card detect pin for changes, sends callback on change

pub fn initialize(&self) -> Result<(), ErrorCode>

pub fn read_blocks( &self, buffer: &'static mut [u8], sector: u32, count: u32, ) -> Result<(), ErrorCode>

pub fn write_blocks( &self, buffer: &'static mut [u8], sector: u32, count: u32, ) -> Result<(), ErrorCode>

Trait Implementations

impl<'a, A: Alarm<'a>> AlarmClient for SDCard<'a, A>

Handle callbacks from the timer

fn alarm(&self)

Callback indicating the alarm time has been reached. The alarm MUST be disabled when this is called. If a new alarm is needed, the client can call Alarm::set_alarm.

impl<'a, A: Alarm<'a>> Client for SDCard<'a, A>

Handle callbacks from the card detection pin

fn fired(&self)

Called when an interrupt occurs. The identifier will be the same value that was passed to enable_interrupt() when the interrupt was configured.

impl<'a, A: Alarm<'a>> SpiMasterClient for SDCard<'a, A>

Handle callbacks from the SPI peripheral

fn read_write_done( &self, write_buffer: SubSliceMut<'static, u8>, read_buffer: Option<SubSliceMut<'static, u8>>, status: Result<usize, ErrorCode>, )

Callback issued when a read/write operation finishes.
