Utility types for modeling chip select pins in a SpiMaster implementation.

Structs

ChipSelectPolar

A convenience wrapper type around Output GPIO pins that implements IntoChipSelect for both ActiveLow and ActiveHigh.

Enums

ActiveHigh

Marks a peripheral as requiring or controller as supporting active high chip select pins.

ActiveLow

Marks a peripheral as requiring or controller as supporting active low chip select pins.

Polarity

Represents the Polarity of a chip-select pin (i.e. whether high or low indicates the peripheral is active).

Traits

ChipSelectActivePolarity

Marker trait indicating whether a peripheral requires active high or low polarity as well as whether a SpiMaster implementation can support either or both polarities.

IntoChipSelect

A type that can be converted to the appropriate type for SpiMaster::ChipSelect for a particular POLARITY.
