Implementations

impl<const BUFFER_SIZE: usize, Pio, ChA, ChB, P0, P1, P2, P3, P4, P5> Cs4272Builder<BUFFER_SIZE, Pio, ChA, ChB, P0, P1, P2, P3, P4, P5>

where P0: OutputPin, P1: AnyPin<Function = Pio::PinFunction>, P2: AnyPin<Function = Pio::PinFunction>, P3: AnyPin<Function = Pio::PinFunction>, P4: AnyPin<Function = Pio::PinFunction>, P5: AnyPin<Function = Pio::PinFunction>, Pio: PIOExt, ChA: SingleChannel, ChB: SingleChannel,

pub fn new( pin_enable: P0, pin_mclk: P1, pin_in: P2, pin_out: P3, pin_ws: P4, pin_clk: P5, pio: Pio, channel_a: ChA, channel_b: ChB, buffer_tx_a: &'static mut [u32; BUFFER_SIZE], buffer_tx_b: &'static mut [u32; BUFFER_SIZE], buffer_rx_a: &'static mut [u32; BUFFER_SIZE], buffer_rx_b: &'static mut [u32; BUFFER_SIZE], ) -> Self

Initialize a new builder.

Requires passing all the necessary pins, DMAs, pio and buffers we need to run the driver.

pub fn sample_rate(self, sample_rate: HertzU32) -> Self

Set the driver sample rate.

The CS4272 chip supports sample rates between 4kHz and 200kHz, defaults to 48kHz.

Note that not all sample rates are possible since the PIO division is based on the microcontroller clock speed, some deviation from the set sample rate should be expected or accounted for.

pub fn system_frequency(self, system_frequency: HertzU32) -> Self

Set the RP235x system frequency.

In case you have changed the frequency of the system you should update this value, defaults to 150MHz.

pub fn set_irq0(self) -> Self

Sets up interrupt DMA_IRQ_0 for the DMA.

pub fn set_irq1(self) -> Self

Sets up interrupt DMA_IRQ_1 for the DMA.

pub fn start( self, resets: &mut RESETS, ) -> Cs4272<BUFFER_SIZE, Pio, ChA, ChB, P0, P1, P2, P3, P4, P5>

Starts the PIO and DMAs, then sets the enable pin high and returns the running driver struct.
