Module lpc82x_hal::gpio

API for General Purpose I/O (GPIO)

The entry point for this API is GPIO. GPIO provides access to the gpio::Handle, which you can use to initialize the GPIO peripheral, and to instances of Pin, which allow you to configure pins.

The GPIO peripheral is described in the user manual, chapter 9.

Examples

Initialize a GPIO pin and set its output to HIGH:

extern crate lpc82x;
extern crate lpc82x_hal;

use lpc82x_hal::prelude::*;
use lpc82x_hal::{
    GPIO,
    SYSCON,
};

let mut peripherals = lpc82x::Peripherals::take().unwrap();

let     gpio   = GPIO::new(&mut peripherals.GPIO_PORT);
let mut syscon = SYSCON::new(&mut peripherals.SYSCON);

let gpio_handle = gpio.handle.init(&mut syscon.handle);

let pio0_12 = unsafe { gpio.pins.pio0_12.affirm_default_state() }
    .as_gpio_pin(&gpio_handle)
    .as_output()
    .set_high();

Assign a pin to the switch matrix and enable a fixed function:

extern crate lpc82x;
extern crate lpc82x_hal;

use lpc82x_hal::prelude::*;
use lpc82x_hal::{
    GPIO,
    SWM,
    SYSCON,
};

let mut peripherals = lpc82x::Peripherals::take().unwrap();

let     gpio   = GPIO::new(&mut peripherals.GPIO_PORT);
let     swm    = SWM::new(&mut peripherals.SWM);
let mut syscon = SYSCON::new(&mut peripherals.SYSCON);

let mut swm_handle = swm.handle.init(&mut syscon.handle);

let vddcmp = unsafe {
    swm.fixed_functions.vddcmp.affirm_default_state()
};
let pio0_6 = unsafe { gpio.pins.pio0_6.affirm_default_state() }
    .as_swm_pin()
    .enable_input_function(vddcmp, &mut swm_handle);
