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

• 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

Type Aliases

• Transaction
  Transaction enum defines possible SPI transactions Re-exported from embedded-hal
