Struct Pio

pub struct Pio { /* private fields */ }

Implementations

impl Pio

pub fn blinking_hello_program_init( &self, sm_number: SMNumber, pin: u32, config: &StateMachineConfiguration, )

Used for the examples in the pico explorer base main.rs file.

pub fn blink_program_init( &self, sm_number: SMNumber, pin: u32, config: &StateMachineConfiguration, )

pub fn sideset_program_init( &self, sm_number: SMNumber, pin: u32, config: &StateMachineConfiguration, )

pub fn hello_program_init( &self, sm_number: SMNumber, pin1: u32, pin2: u32, config: &StateMachineConfiguration, )

pub fn pwm_program_init( &self, sm_number: SMNumber, pin: u32, pwm_period: u32, config: &StateMachineConfiguration, )

pub fn spi_program_init( &self, sm_number: SMNumber, clock_pin: u32, in_pin: u32, out_pin: u32, config: &StateMachineConfiguration, )

pub fn read_instr(&self, sm_number: SMNumber) -> u32

Returns current instruction running on the state machine.

pub fn read_sideset_reg(&self, sm_number: SMNumber)

pub fn read_dbg_padout(&self) -> u32

pub fn read_fdebug(&self, tx: bool, stall: bool) -> u32

impl Pio

pub fn gpio_init(&self, pin: &RPGpioPin<'_>)

Setup the function select for a GPIO to use output from the given PIO instance.

pub fn new_pio0() -> Self

Create a new PIO0 struct.

pub fn new_pio1() -> Self

Create a new PIO1 struct.

pub fn sm(&self, sm_number: SMNumber) -> &StateMachine

Get state machine

pub fn set_irq_source( &self, irq_index: u32, interrupt_source: InterruptSources, enabled: bool, )

Enable/Disable a single source on a PIO’s IRQ index.

pub fn interrupt_get(&self, irq_num: u32) -> bool

Checks if a PIO interrupt is set.

pub fn interrupt_clear(&self, irq_num: u32)

Clear a PIO interrupt.

pub fn handle_interrupt(&self)

Handle interrupts

pub fn add_program( &self, origin: Option<usize>, program: &[u8], ) -> Result<LoadedProgram, ProgramError>

Adds a program to PIO. Call this with add_program(Some(0), include_bytes!("path_to_file")). => origin: the address in the PIO instruction memory to start the program at or None to find an empty space => program: the program to load into the PIO Returns LoadedProgram which contains information about program location and length.

pub fn add_program16( &self, origin: Option<usize>, program: &[u16], ) -> Result<LoadedProgram, ProgramError>

Adds a program to PIO. Takes &[u16] as input, cause pio-asm operations are 16bit. => origin: the address in the PIO instruction memory to start the program at or None to find an empty space => program: the program to load into the PIO Returns LoadedProgram which contains information about program location and size.

pub fn clear_instr_registers(&self)

Clears all of a PIO instance’s instruction memory.

pub fn init(&self)

Initialize a new PIO with the same default configuration for all four state machines.
