Module stm32f3xx_hal::gpio

General Purpose Input / Output

To use the GPIO pins, you first need to configure the GPIO bank (GPIOA, GPIOB, ...) that you are interested in. This is done using the GpioExt::split function.

let dp = pac::Peripherals::take().unwrap();
let rcc = dp.RCC.constrain();

let mut gpioa = dp.GPIOA.split(&mut rcc.ahb);

The resulting Parts struct contains one field for each pin, as well as some shared registers.

To use a pin, first use the relevant into_... method of the pin.

let pa0 = gpioa.pa0.into_push_pull_output(&mut gpioa.moder, &mut gpioa.otyper);

And finally, you can use the functions from the InputPin or OutputPin traits in embedded_hal

For a complete example, see examples/toggle.rs
