Module rp2040_hal::sio

Expand description

Single Cycle Input and Output (SIO)

To be able to partition parts of the SIO block to other modules:

use rp2040_hal::{gpio::Pins, pac, sio::Sio};

let mut peripherals = pac::Peripherals::take().unwrap();
let sio = Sio::new(peripherals.SIO);

And then for example

let pins = Pins::new(peripherals.IO_BANK0, peripherals.PADS_BANK0, sio.gpio_bank0, &mut peripherals.RESETS);

Structs

DivResult

Result of divide/modulo operation

HwDivider

Marker struct for ownership of divide/modulo module

Sio

Struct containing ownership markers for managing ownership of the SIO registers.

SioFifo

Marker struct for ownership of SIO FIFO

SioGpioBank0

Marker struct for ownership of SIO gpio bank0

SioGpioQspi

Marker struct for ownership of SIO gpio qspi

Spinlock

Hardware based spinlock.

Traits

SpinlockValid

This type is just used to limit us to Spinlocks 0..=31

Functions

spinlock_state

Returns the current state of the spinlocks. Each index corresponds to the associated spinlock, e.g. if index 5 is set to true, it means that Spinlock5 is currently locked.
