Struct stm32f412g::clocks::hse::Hse

pub struct Hse<'a> { /* private fields */ }

Main HSE clock structure

Implementations

impl<'a> Hse<'a>

pub fn enable(&self, source: HseMode) -> Result<(), ErrorCode>

Start the HSE clock.

Errors

• Err(ErrorCode::BUSY): disabling the HSE clock took to long. Retry to ensure it is running

pub fn disable(&self) -> Result<(), ErrorCode>

Stop the HSE clock.

Errors

• Err(ErrorCode::FAIL): if the HSE clock is configured as the system clock.
• Err(ErrorCode::BUSY): disabling the HSE clock took to long. Retry to ensure it is not running.

pub fn is_enabled(&self) -> bool

Check whether the HSE clock is enabled or not.

Returns

• false: the HSE clock is not enabled
• true: the HSE clock is enabled

pub fn get_frequency_mhz(&self) -> Option<usize>

Get the frequency in MHz of the HSE clock.

Returns

• Some(frequency_mhz): if the HSE clock is enabled.
• None: if the HSE clock is disabled.

pub fn set_frequency_mhz(&self, frequency: usize)

Set the frequency in MHz of the HSE clock.

Parameters

• frequency: HSE frequency in MHz
