Module capsules::sdcard

Provides driver for accessing an SD Card and a userspace Driver.

This allows initialization and block reads or writes on top of SPI.

Usage

let sdcard_spi = static_init!(
    capsules::virtual_spi::VirtualSpiMasterDevice<'static, usart::USART>,
    capsules::virtual_spi::VirtualSpiMasterDevice::new(mux_spi,
                                                       Some(&sam4l::gpio::PA[13])));
let sdcard_virtual_alarm = static_init!(
    VirtualMuxAlarm<'static, sam4l::ast::Ast>,
    VirtualMuxAlarm::new(mux_alarm));

let sdcard = static_init!(
    capsules::sdcard::SDCard<'static, VirtualMuxAlarm<'static, sam4l::ast::Ast>>,
    capsules::sdcard::SDCard::new(sdcard_spi,
                                  sdcard_virtual_alarm,
                                  Some(&sam4l::gpio::PA[17]),
                                  &mut capsules::sdcard::TXBUFFER,
                                  &mut capsules::sdcard::RXBUFFER));
sdcard_spi.set_client(sdcard);
sdcard_virtual_alarm.set_client(sdcard);
sam4l::gpio::PA[17].set_client(sdcard);

let sdcard_driver = static_init!(
    capsules::sdcard::SDCardDriver<'static, VirtualMuxAlarm<'static, sam4l::ast::Ast>>,
    capsules::sdcard::SDCardDriver::new(sdcard, &mut capsules::sdcard::KERNEL_BUFFER));
sdcard.set_client(sdcard_driver);

Structs

App	Holds buffers and whatnot that the application has passed us.
SDCard	SD Card capsule, capable of being built on top of by other kernel capsules
SDCardDriver	Application driver for SD Card capsule, layers on top of SD Card capsule This is used if the SDCard is going to be attached directly to userspace syscalls. SDCardDriver can be ignored if another capsule is going to build off of the SDCard instead

Enums

AlarmState	Alarm states
ErrorCode	Error codes returned if an SD card transaction fails
SDCardType	SD card types, determined during initialization
SDCmd	SD card command codes
SDResponse	SD card response codes
SpiState	SPI states

Constants

DATA_TOKEN
INITIALIZING_STATUS
SUCCESS_STATUS

Statics

KERNEL_BUFFER	Buffer for SD card driver, assigned in board main.rs files
RXBUFFER
TXBUFFER	Buffers used for SD card transactions, assigned in board main.rs files Constraints:

Traits
