Implementations§

Source§

impl<P> PIO<P>
where P: PIOExt,

Source

pub fn free( self, _sm0: UninitStateMachine<(P, SM0)>, _sm1: UninitStateMachine<(P, SM1)>, _sm2: UninitStateMachine<(P, SM2)>, _sm3: UninitStateMachine<(P, SM3)>, ) -> P

Free this instance.

All output pins are left in their current state.

Source

pub fn irq<const IRQ: usize>(&self) -> Interrupt<'_, P, IRQ>

This PIO’s interrupt by index.

Source

pub fn irq0(&self) -> Interrupt<'_, P, 0>

This PIO’s IRQ0 interrupt.

Source

pub fn irq1(&self) -> Interrupt<'_, P, 1>

This PIO’s IRQ1 interrupt.

Source

pub fn get_irq_raw(&self) -> u8

Get raw irq flags.

The PIO has 8 IRQ flags, of which 4 are visible to the host processor. Each bit of flags corresponds to one of the IRQ flags.

Source

pub fn clear_irq(&self, flags: u8)

Clear PIO’s IRQ flags indicated by the bits.

The PIO has 8 IRQ flags, of which 4 are visible to the host processor. Each bit of flags corresponds to one of the IRQ flags.

Source

pub fn force_irq(&self, flags: u8)

Force PIO’s IRQ flags indicated by the bits.

The PIO has 8 IRQ flags, of which 4 are visible to the host processor. Each bit of flags corresponds to one of the IRQ flags.

Source

pub fn install( &mut self, p: &Program<rp235x_hal::::pio::{impl#6}::install::{constant#0}>, ) -> Result<InstalledProgram<P>, InstallError>

Allocates space in instruction memory and installs the program.

The function returns a handle to the installed program that can be used to configure a StateMachine via PIOBuilder. The program can be uninstalled to free instruction memory via uninstall() once the state machine using the program has been uninitialized.

Note: We use the RP2040 program size constant, but the RP2350 has the same size instruction memory.

§Safety

PIOExt is marked send and should be the only object allowed to access pio.instr_mem

Source

pub fn uninstall(&mut self, p: InstalledProgram<P>)

Removes the specified program from instruction memory, freeing the allocated space.
