Struct stm32f412g::clocks::hsi::Hsi

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

Main HSI clock structure

Implementations

impl<'a> Hsi<'a>

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

Start the HSI clock.

Errors

• Err(ErrorCode::BUSY): if enabling the HSI clock took too long. Recall this method to ensure the HSI clock is running.

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

Stop the HSI clock.

Errors

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

pub fn is_enabled(&self) -> bool

Check whether the HSI clock is enabled or not.

Returns

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

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

Get the frequency in MHz of the HSI clock.

Returns

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