Module stm32h7xx_hal::delay

Delay providers

There are currently two delay providers. In general you should prefer to use Delay, however if you do not have access to SYST you can use DelayFromCountDownTimer with any timer that implements the CountDown trait. This can be useful if you’re using RTIC’s schedule API, which occupies the SYST peripheral.

Examples

Delay

let mut delay = Delay::new(core.SYST, device.clocks);

delay.delay_ms(500);

// Release SYST from the delay
let syst = delay.free();

DelayFromCountDownTimer

let timer2 = device
    .TIM2
    .timer(1.kHz(), device.peripheral.TIM2, &mut device.clocks);
let mut delay = DelayFromCountDownTimer::new(timer2);

delay.delay_ms(500);

// Release the timer from the delay
let timer2 = delay.free();
