Struct matrix_rhal::gpio::Gpio

pub struct Gpio<'a> { /* fields omitted */ }

Controls the GPIO pins on a MATRIX device.

Methods

impl<'a> Gpio<'a>

pub fn new(bus: &'a Bus) -> Gpio

Returns an instance of GPIO.

impl<'a> Gpio<'a>

pub fn get_state(&self, pin: u8) -> bool

Returns the current digital value of a MATRIX GPIO pin (0->15).

pub fn get_states(&self) -> [bool; 16]

Returns the current digital value of every MATRIX GPIO pin (0->15)

impl<'a> Gpio<'a>

pub fn set_config<T>(&self, pin: u8, config: T) -> Result<(), Error> where
    T: PinConfig, 

Configure a specific pin's mode, function, state, etc..

pub fn set_configs<T>(&self, pins: &[u8], config: T) -> Result<(), Error> where
    T: PinConfig, 

Configure multiple pins' mode, function, state, etc..

pub fn set_prescaler(&self, bank: usize, prescaler: u16) -> Result<(), Error>

Set the prescaler value for a specific bank

pub fn set_pwm(
    &self,
    pin: u8,
    frequency: f32,
    percentage: f32
) -> Result<(), Error>

Set the Pulse Width Modulation output for a pin.

pub fn set_servo_angle(
    &self,
    pin: u8,
    angle: u32,
    min_pulse_ms: f32
) -> Result<(), Error>

Abstraction over set_pwm to easily control a servo.

min_pulse_ms accepts values from 0 to 1.5. Inputs outside this range will be set to the closest valid number.

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
