Struct Parts 

pub struct Parts<'a, SD>
where
    SD: Comms + 'a,
{
    pub spi: SPI<'a, SD>,
    pub cs: CS<'a, SD>,
    pub pin_a: PinA<'a, SD>,
    pub pin_b: PinB<'a, SD>,
}

Parts is a container for the various parts of a SPIDriver that can be used separately via distinct HAL traits.

The HAL objects inside a particular Parts all share a single underlying communications channel, so it is not possible to access them concurrently on multiple threads. Instead, coordinate all interactions with a single SPIDriver on a single thread.

Fields

spi: SPI<'a, SD>

spi is an implementation of the blocking SPI Write and Transfer traits with an 8-bit word size.

cs: CS<'a, SD>

cs is an implementation of the digital I/O OutputPin trait that controls the SPIDriver’s Chip Select pin.

Setting this pin to low is implemented as “select” on the SPIDriver and setting it to high is implemented as “unselect”, for consistency with the way driver crates tend to expect a CS pin to behave.

pin_a: PinA<'a, SD>

pin_a is an implementation of the digital I/O OutputPin trait that controls the SPIDriver’s auxillary output pin “A”.

pin_b: PinB<'a, SD>

pin_a is an implementation of the digital I/O OutputPin trait that controls the SPIDriver’s auxillary output pin “B”.
