Crate embassy_stm32

Feature flags

• rt (enabled by default) — Enable stm32-metapac’s rt feature

• defmt — Use defmt for logging

• memory-x — Automatically generate memory.x file using stm32-metapac

• nightly — Enable nightly-only features

• unstable-pac — Re-export stm32-metapac at embassy_stm32::pac. This is unstable because semver-minor (non-breaking) releases of embassy-stm32 may major-bump (breaking) the stm32-metapac version. If this is an issue for you, you’re encouraged to directly depend on a fixed version of the PAC. There are no plans to make this stable.

• unstable-traits — Implement embedded-hal 1.0 alpha traits. Implement embedded-hal-async traits if nightly is set as well.

Time

• time — Enables additional driver features that depend on embassy-time

• time-driver-any — Use any time driver

• time-driver-tim2 — Use TIM2 as time driver

• time-driver-tim3 — Use TIM3 as time driver

• time-driver-tim4 — Use TIM4 as time driver

• time-driver-tim5 — Use TIM5 as time driver

• time-driver-tim12 — Use TIM12 as time driver

• time-driver-tim15 — Use TIM15 as time driver

Analog Switch Pins (Pxy_C) on STM32H7 series

Get PXY and PXY_C singletons. Digital impls are on PXY, Analog impls are on PXY_C If disabled, you get only the PXY singleton. It has both digital and analog impls.

• split-pa0 — Split PA0

• split-pa1 — Split PA1

• split-pc2 — Split PC2

• split-pc3 — Split PC3

• _split-pins-enabled — internal use only

Chip-selection features

Select your chip by specifying the model as a feature, e.g. stm32c011d6. Check the Cargo.toml for the latest list of supported chips.

Important: Do not forget to adapt the target chip in your toolchain, e.g. in .cargo/config.toml.
