Module hse

HSE (high-speed external) clock driver for the STM32F4xx family. ¹

Usage

For the purposes of brevity, any error checking has been removed. In real applications, always check the return values of the Hse methods.

First, get a reference to the Hse struct:

let hse = &base_peripherals.clocks.hse;

Start the clock

hse.enable(stm32f429zi::rcc::HseMode::BYPASS);

Set the clock frequency

hse.set_frequency_mhz(8);

Stop the clock

hse.disable();

Check if the clock is enabled

if hse.is_enabled() {
    /* Do something */
} else {
    /* Do something */
}

Get the frequency of the clock

let hse_frequency_mhz = hse.get_frequency_mhz().unwrap();
