Struct SpiBusResources 

pub struct SpiBusResources<'d> {
    pub spi: SPI2<'d>,
    pub dma: DMA_CH2<'d>,
    pub sck: GPIO40<'d>,
    pub mosi: GPIO14<'d>,
    pub miso: GPIO39<'d>,
    pub sd_cs: GPIO12<'d>,
    pub ext_cs: GPIO5<'d>,
}

The shared SPI bus and both of its chip selects. sd is in crate::sd.

Fields

spi: SPI2<'d>

dma: DMA_CH2<'d>

Implementations

impl<'d> SpiBusResources<'d>

pub fn reborrow(&mut self) -> SpiBusResources<'_>

A copy of this group that lives only as long as the borrow, to lend the hardware to a function without giving it up.

impl<'d> SpiBusResources<'d>

pub fn sd(&mut self) -> Result<Sd<'_>, Error>

Initialises the microSD card, giving it the shared bus exclusively, read-only. Fails if no card is inserted or it doesn’t respond.

The returned Sd borrows the bus; drop it and the bus is free for the EXT header or another sd call.
