Struct embassy_rp::pio::Common

pub struct Common<'d, PIO: Instance> { /* private fields */ }

PIO handle.

Implementations

impl<'d, PIO: Instance> Common<'d, PIO>

pub fn load_program<const SIZE: usize>( &mut self, prog: &Program<SIZE> ) -> LoadedProgram<'d, PIO>

Load a PIO program. This will automatically relocate the program to an available chunk of free instruction memory if the program origin was not explicitly specified, otherwise it will attempt to load the program only at its origin.

pub fn try_load_program<const SIZE: usize>( &mut self, prog: &Program<SIZE> ) -> Result<LoadedProgram<'d, PIO>, LoadError>

Load a PIO program. This will automatically relocate the program to an available chunk of free instruction memory if the program origin was not explicitly specified, otherwise it will attempt to load the program only at its origin.

pub unsafe fn free_instr(&mut self, instrs: InstanceMemory<'_, PIO>)

Free instruction memory. This is always possible but unsafe if any state machine is still using this bit of memory.

pub fn set_input_sync_bypass<'a>(&'a mut self, bypass: u32, mask: u32)

Bypass flipflop synchronizer on GPIO inputs.

pub fn get_input_sync_bypass(&self) -> u32

Get bypass configuration.

pub fn make_pio_pin( &mut self, pin: impl Peripheral<P = impl PioPin + 'd> + 'd ) -> Pin<'d, PIO>

Register a pin for PIO usage. Pins will be released from the PIO block (i.e., have their FUNCSEL reset to NULL) when the Common and all StateMachines for this block have been dropped. Other members of Pio do not keep pin registrations alive.

pub fn apply_sm_batch(&mut self, f: impl FnOnce(&mut PioBatch<'d, PIO>))

Apply changes to all state machines in a batch.

Trait Implementations

impl<'d, PIO: Instance> Drop for Common<'d, PIO>

fn drop(&mut self)

Executes the destructor for this type.
