Struct PioGSpi 

pub struct PioGSpi<'a> { /* private fields */ }

The gSPI PIO peripheral driver

Implementations

impl<'a> PioGSpi<'a>

pub fn new( pio: &'a Pio, dma: DmaChannel<'a>, clock_pin: u32, dio_pin: u32, cs_pin: &'a RPGpioPin<'a>, sm_number: SMNumber, ) -> Self

Create a new PioCyw43Spi instance

pub fn sm_number(&self) -> SMNumber

Return SM number

pub fn set_irq_client(&self, client: &'a dyn Client)

pub fn init(&self)
