Crate driver_pal 

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 driver_pal::wrapper::Wrapper type is provided to wrap existing SPI implementations in this driver_pal::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

hal

mock

wrapper

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

Enums
