Module kernel::hil::spi[][src]

Interfaces for SPI master and slave communication.

Re-exports

use core::option::Option;
use returncode::ReturnCode;

Enums

ClockPhase

Which clock edge values are sampled on

ClockPolarity

Values for the clock polarity (idle state or CPOL)

DataOrder

Values for the ordering of bits

Traits

SpiMaster

The SpiMaster trait for interacting with SPI slave devices at a byte or buffer level.

SpiMasterClient
SpiMasterDevice

SPIMasterDevice provides a chip-specific interface to the SPI Master hardware. The interface wraps the chip select line so that chip drivers cannot communicate with different SPI devices.

SpiSlave
SpiSlaveClient
SpiSlaveDevice

SPISlaveDevice provides a chip-specific interface to the SPI Slave hardware. The interface wraps the chip select line so that chip drivers cannot communicate with different SPI devices.
