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.

rcc: Config

RCC config.

enable_debug_during_sleep: bool

Enable debug during sleep and stop.

May increase power consumption. Defaults to true.

enable_independent_io_supply: bool

On low-power boards (eg. stm32l4, stm32l5, stm32wba and stm32u5), some GPIO pins are powered by an auxiliary, independent power supply (VDDIO2), which needs to be enabled before these pins can be used.

May increase power consumption. Defaults to true.

enable_analog_switch_booster: bool

Enable the I/O analog switch voltage booster.

The analog switch between a GPIO and the ADC (or comparator, or operational amplifier) has a much higher resistance when the analog supply is low, which distorts conversions of pin channels unless they are given a much longer sample time. The reference manuals ask for this booster below 2.4 V (2.7 V on the H5, H7 and H7RS). It draws extra current, so it is off by default.

On boards where only VDDA is low and VDD is not, the analog switches can instead be supplied from VDD, which this option does not do.

enable_independent_analog_supply: bool

On the U5 series all analog peripherals are powered by a separate supply.

gpdma_interrupt_priority: Priority

GPDMA interrupt priority.

Defaults to P0 (highest).

enable_ucpd1_dead_battery: bool

Enables UCPD1 dead battery functionality.

Defaults to false (disabled).
