Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

hse: Option<Hertz>

Frequency of HSE oscillator 4MHz to 32MHz

bypass_hse: bool

Bypass HSE for an external clock

sysclk: Option<Hertz>

Frequency of the System Clock

hclk: Option<Hertz>

Frequency of AHB bus

pclk1: Option<Hertz>

Frequency of APB1 bus

• Max frequency 36MHz

pclk2: Option<Hertz>

Frequency of APB2 bus

• Max frequency with HSE is 72MHz
• Max frequency without HSE is 64MHz

pll48: bool

USB clock setup It is valid only when,

• HSE is enabled,
• The System clock frequency is either 48MHz or 72MHz
• APB1 clock has a minimum frequency of 10MHz

adc: Option<AdcClockSource>

ADC clock setup

• For AHB, a psc of 4 or less must be used

adc34: Option<AdcClockSource>

ADC clock setup

• For AHB, a psc of 4 or less must be used

ls: LsConfig

Trait Implementations

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.
