Getting Started

The examples folder contains several example programs. To compile them, one must specify the target device as cargo feature:

$ cargo build --features=py32f030 --example=blinky

To use py32f0xx-hal as a dependency in a standalone project the target device feature must be specified in the Cargo.toml file:

[dependencies]
embedded-hal = "1"
nb = "1"
cortex-m = "0.7.7"
cortex-m-rt = "0.7.3"
# Panic behaviour, see https://crates.io/keywords/panic-impl for alternatives
panic-halt = "0.2.0"
py32f0xx-hal = { version = "0.6.1", features = ["py32f030"] }

Optional Features

• rtic this feature includes a monotonic timer module for use with that crate
• defmt Adds derive(defmt::Format) to Error types in this crate

If you are unfamiliar with embedded development using Rust, there are a number of fantastic resources available to help.

• Embedded Rust Documentation
• The Embedded Rust Book
• Rust Embedded FAQ
• rust-embedded/awesome-embedded-rust

Minimum supported Rust version

The minimum supported Rust version is the latest stable release. Older versions may compile, especially when some features are not used in your application.
