Function lpspi

pub fn lpspi<Sdo, Sdi, Sck, Pcs0, const N: u8>(
    instance: Instance<N>,
    pins: LpspiPins<Sdo, Sdi, Sck, Pcs0>,
    baud: u32,
) -> Lpspi<LpspiPins<Sdo, Sdi, Sck, Pcs0>, N>
where
    Sdo: Pin<Signal = Sdo, Module = Const<N>>,
    Sdi: Pin<Signal = Sdi, Module = Const<N>>,
    Sck: Pin<Signal = Sck, Module = Const<N>>,
    Pcs0: Pin<Signal = Pcs0, Module = Const<N>>,

Create a LPSPI peripheral.

baud is the SCK frequency, in Hz. Consider using explicit type annotations, as demonstrated below, to simplify any errors from the compiler.

This helper assumes that the LPSPI clock frequency equals LPSPI_FREQUENCY.

use teensy4_bsp as bsp;
use bsp::board;

let board::T40Resources { lpspi4, pins, .. }
    = board::t40(board::instances());

let mut lpspi4: board::Lpspi4 = board::lpspi(
    lpspi4,
    board::LpspiPins {
        sdo: pins.p11,
        sdi: pins.p12,
        sck: pins.p13,
        pcs0: pins.p10,
    },
