stm32g0xx-hal
stm32g0xx-hal contains a multi device hardware abstraction on top of the peripheral access API for the STMicro STM32G0 series microcontrollers. The selection of the MCU is done by feature gates, typically specified by board support crates.

Usage
This crate will eventually contain support for multiple microcontrollers in the
stm32g0 family. Which specific microcontroller you want to build for has to be
specified with a feature, for example stm32g070.
Building an Example
If you are compiling the crate on its own for development or running examples, specify your microcontroller on the command line. For example:
cargo build --example blinky --features stm32g071
Using as a Dependency
When using this crate as a dependency in your project, the microcontroller can
be specified as part of the Cargo.toml definition.
[dependencies.stm32g0xx-hal]
version = "0.1.1"
features = ["rt", "stm32g081"]
