Implementations

impl Clocks

pub fn setup(&self, rcc: &mut RCC, flash: &mut FLASH) -> Result<(), SpeedError>

Setup clocks and return a Valid status if the config is valid. Return Invalid, and don’t setup if not. https://docs.rs/stm32f3xx-hal/0.5.0/stm32f3xx_hal/rcc/struct.CFGR.html Use the STM32CubeIDE Clock Configuration tab to help.

pub fn calc_speeds(&self) -> Speeds

Calculate clock speeds from a given config. Everything is in Mhz. todo: Handle fractions of mhz. Do floats.

pub fn validate(&self) -> Validation

Check if valid.

pub fn validate_usb(&self) -> Validation

pub fn make_rcc_clocks(&self) -> Clocks

Make a clocks struct from the rcc module, that we can pass into existing modules that use its speeds, like i2c, serial, timer etc.

pub fn full_speed() -> Self

This preset configures clocks with a HSE, a 72Mhz sysclck. All peripheral clocks are at 72Mhz, except for APB1, which is at and 36Mhz. USB is set to 48Mhz. HSE output is not bypassed.

Trait Implementations

impl Default for Clocks

fn default() -> Self

This default configures clocks with a HSE, a 48Mhz sysclck. All peripheral clocks are at 48 Mhz, except for APB1, which is at and 24Mhz. USB is set to 48Mhz. HSE output is not bypassed.
