Function stm32wlxx_hal::rcc::setup_lsi

source · 
pub unsafe fn setup_lsi(rcc: &mut RCC, pre: LsiPre)
Expand description

Setup the LSI clock and wait for completion.

This will temporarily disable the LSI clock if the prescaler needs to be changed.

Safety

  1. Ensure there are no peripherals using the LSI clock source before calling this function.

Example

use stm32wlxx_hal::{
    pac,
    rcc::{setup_lsi, LsiPre},
};

let mut dp: pac::Peripherals = pac::Peripherals::take().unwrap();
unsafe { setup_lsi(&mut dp.RCC, LsiPre::Div1) };
