rtic_monotonics

Module stm32

source
Expand description

Monotonic implementations for STM32 chips.

Not all timers are available on all parts. Ensure that only available timers are exposed by having the correct stm32* feature enabled for rtic-monotonics.

§Example

use rtic_monotonics::stm32::prelude::*;

// Define the monotonic and set it to 1MHz tick rate
stm32_tim2_monotonic!(Mono, 1_000_000);

fn init() {
    // If using `embassy-stm32` HAL, timer clock can be read out like this:
    let timer_clock_hz = embassy_stm32::peripherals::TIM2::frequency();
    // Or define it manually if you are using other HAL or know correct frequency:
    let timer_clock_hz = 64_000_000;

    // Start the monotonic
    Mono::start(timer_clock_hz);
}

async fn usage() {
    loop {
         // Use the monotonic
         let timestamp = Mono::now();
         Mono::delay(100.millis()).await;
    }
}
