Struct Rx 

pub struct Rx<const N: u8, const WORD_SIZE: u8, const FRAME_SIZE: usize, PACKING: Packing<WORD_SIZE>> { /* private fields */ }

A SAI receive half

Implementations

impl<const N: u8, const WORD_SIZE: u8, const FRAME_SIZE: usize, PACKING: Packing<WORD_SIZE>> Rx<N, WORD_SIZE, FRAME_SIZE, PACKING>

pub fn set_enable(&mut self, en: bool)

Enable/Disable transmission

pub fn interrupts(&self) -> Interrupts

Return the interrupt flags.

The interrupt flags indicate the reasons that this peripheral may generate an interrupt.

pub fn set_interrupts(&mut self, interrutps: Interrupts)

Set the interrupt flags for this SAI transmitter.

pub fn status(&mut self) -> Status

Get the status register of the transmitter, this can be used in conjunction with status field masks to determine the state of the SAI peripheral.

pub fn clear_status(&mut self, flags: Status)

Clear status error flags

pub fn reg_dump(&mut self) -> [u32; 6]

Get a dump of the Rx configuration registers

pub fn fifo_position(&mut self, chan: usize) -> (u32, u32)

Get the FIFO write and read position

use imxrt_ral::sai::{SAI1, RCSR};
use imxrt_hal::sai::{Rx, PackingNone, Sai, SaiConfig};
let sai = Sai::without_pins(unsafe { SAI1::instance() }, 0, 0);
let (Some(mut sai_rx), None) = sai.split::<16, 2, PackingNone>(&SaiConfig::i2s(8)) else { panic!() };

let (write_pos, read_pos) = sai_rx.fifo_position(0);

impl<const N: u8, const FRAME_SIZE: usize> Rx<N, 32, FRAME_SIZE, PackingNone>

pub fn read_frame(&mut self, chan: usize, frame: &mut [u32; FRAME_SIZE])

Read without checks or blocking a single audio frame from channels FIFO

impl<const N: u8, const FRAME_SIZE: usize> Rx<N, 16, FRAME_SIZE, PackingNone>

pub fn read_frame(&mut self, chan: usize, frame: &mut [u16; FRAME_SIZE])

Read without checks or blocking a single audio frame from channels FIFO

impl<const N: u8, const FRAME_SIZE: usize> Rx<N, 8, FRAME_SIZE, PackingNone>

pub fn read_frame(&mut self, chan: usize, frame: &mut [u8; FRAME_SIZE])

Read without checks or blocking a single audio frame from channels FIFO
