Module stm32f412g::clocks::hsi

HSI (high-speed internal) 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 Hsi methods.

First, get a reference to the Hsi struct:

let hsi = &peripherals.stm32f4.clocks.hsi;

Start the clock

hsi.enable();

Stop the clock

hsi.disable();

Check if the clock is enabled

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

Get the frequency of the clock

let hsi_frequency_mhz = hsi.get_frequency().unwrap();
