Function stm32wlxx_hal::rcc::cpu2_systick_hz

pub fn cpu2_systick_hz(rcc: &RCC, src: SystClkSource) -> u32

Available on crate features stm32wl5x_cm4 or stm32wl5x_cm0p only.

Calculate the current CPU2 systick frequency in hertz

Fractional frequencies will be rounded down.

Example

Created a systick based delay structure.

use stm32wlxx_hal::{
    cortex_m::{delay::Delay, peripheral::syst::SystClkSource},
    pac,
    rcc::cpu2_systick_hz,
};

let mut dp: pac::Peripherals = pac::Peripherals::take().unwrap();
let cp: pac::CorePeripherals = pac::CorePeripherals::take().unwrap();

// Delay constructor will set the clock source to core
// note: this code is only valid if running on CPU2
//       cpu_systick_hz is better for this use-case
let mut delay: Delay = Delay::new(cp.SYST, cpu2_systick_hz(&dp.RCC, SystClkSource::Core));
delay.delay_ms(100);
