Struct stabilizer::hardware::adc::Adc0Input

pub struct Adc0Input { /* private fields */ }

Represents data associated with ADC.

Implementations

impl Adc0Input

pub fn new( spi: Spi<SPI2, Enabled, u16>, trigger_stream: Stream0<DMA1>, data_stream: Stream1<DMA1>, clear_stream: Stream2<DMA1>, trigger_channel: Channel1, clear_channel: Channel1, batch_size: usize ) -> Self

Construct the ADC input channel.

Args

• spi - The SPI interface used to communicate with the ADC.
• trigger_stream - The DMA stream used to trigger each ADC transfer by writing a word into the SPI TX FIFO.
• data_stream - The DMA stream used to read samples received over SPI into a data buffer.
• clear_stream - The DMA stream used to clear the EOT flag in the SPI peripheral.
• trigger_channel - The ADC sampling timer output compare channel for read triggers.
• clear_channel - The shadow sampling timer output compare channel used for clearing the SPI EOT flag.

pub fn start(&mut self)

Enable the ADC DMA transfer sequence.

pub fn with_buffer<F, R>(&mut self, f: F) -> Result<R, DMAError>

where F: FnOnce(&mut &'static mut [u16]) -> R,

Wait for the transfer of the currently active buffer to complete, then call a function on the now inactive buffer and acknowledge the transfer complete flag.

NOTE(unsafe): Memory safety and access ordering is not guaranteed (see the HAL DMA docs).

Trait Implementations

impl Mutex for Adc0Input

type Data = &'static mut [u16]

Data protected by the mutex.

fn lock<R>(&mut self, f: impl FnOnce(&mut Self::Data) -> R) -> R

Creates a critical section and grants temporary access to the protected data.
