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::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

Traits

Busy	Busy trait for peripherals that support a busy signal
ChipSelect	Chip Select trait for peripherals supporting manual chip select
Hal	HAL trait abstracts commonly required functions for SPI peripherals
ManagedChipSelect	ManagedChipSelect marker trait indicates CS is managed by the driver
PrefixRead	PrefixRead trait provides a higher level, write then read function
PrefixWrite	PrefixWrite trait provides higher level, writye then write function
Ready	Ready trait for peripherals that support a ready signal (or IRQ)
Reset	Reset trait for peripherals that have a reset or shutdown pin
