Implementations

impl Clocks

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

Setup common 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 hse_preset() -> Self

This preset configures common with a 8Mhz HSE, a 80Mhz sysclck. All peripheral clocks are at 80Mhz. HSE output is not bypassed.

Trait Implementations

impl ClockCfg for Clocks

fn sysclk(&self) -> u32

System clock speed, in Hz.

fn hclk(&self) -> u32

HCLK speed, in Hz. Ie AHB bus, core, memory, and DMA.

fn systick(&self) -> u32

Cortex System timer speed, in Hz.

fn usb(&self) -> u32

USB speed, in Hz.

fn apb1(&self) -> u32

APB1 peripheral common speed, in Hz.

fn apb1_timer(&self) -> u32

APB1 timer common speed, in Hz.

fn apb2(&self) -> u32

APB2 timer common speed, in Hz.

fn apb2_timer(&self) -> u32

APB2 peripheral common speed, in Hz.

fn validate_speeds(&self) -> ClocksValid

Validate that the clocks speeds are all within the acceptable range for the MCU // todo Separate USB validation? back to Validation enum, or keep it simple?

impl Default for Clocks

fn default() -> Self

This default configures common with a HSI, a 80Mhz sysclck (l4/5). All peripheral clocks are at 80Mhz (l4/5). 168Mhz for G4.
