Crate embedded_spi

Embedded SPI helper package This defines a higher level Transactional SPI interface, as well as an SPI Transaction enumeration that more closely map to the common uses of SPI peripherals, as well as some other common driver helpers.

An embedded_spi::wrapper::Wrapper type is provided to wrap existing SPI implementations in this embedded_spi::Transactional interface, as well as a set of helpers for C compatibility enabled with the compat feature, and a basic mocking adaptor enabled with the mock feature.

Modules

mock
wrapper	Transactional SPI wrapper implementation This provides a Wrapper type that is generic over an embedded_hal::blocking::spi and embedded_hal::digital::v2::OutputPin to provide a transactional API for SPI transactions.

Enums

Error	Error type combining SPI and Pin errors for utility
PinState	PinState enum used for busy indication
Transaction	Transaction enum defines possible SPI transactions

Traits

Busy	Busy trait for peripherals that support a busy signal
Ready	Ready trait for peripherals that support a ready signal (or IRQ)
Reset	Reset trait for peripherals that have a reset or shutdown pin
Transactional	Transaction trait provides higher level, transaction-based, SPI constructs These are executed in a single SPI transaction (without de-asserting CS).
