This repository holds various crates that support/enable working with Microchip (nee Atmel) samd11, samd21, samd51 and same5x based devices using Rust.

The Peripheral Access Crates (PACs) are automatically generated from Microchip SVD files, and provide low-level access to the peripherals specified by a device's SVD file.
Board Support Packages (BSPs) are provided for popular development boards, which rename pins to match silk screens or Arduino pin assignments, add helpers for initialization, and re-export the atsamd-hal crate. The BSPs included in atsamd-rs are separated in to two tiers: Tier 1 BSPs use the latest version of atsamd-hal, Tier 2 BSPs use a specific version of atsamd-hal that is not necessarily the latest.
* Tier 1 BSP
The BSPs include examples to quickly get up and running with the board. Building the examples requires changing directory into one of the board support package directories, and some examples will require additional features:
$ cd boards/metro_m0
$ cargo build --examples --features="usb"A new firmware can be made from one of the examples:
- Create a new Cargo package for the firmware
cargo new my_firmware,cd my_firmware - Copy the BSP example source file
cp feather_m0/examples/blinky_basic.rs src/main.rs - Copy Cargo config and memory layout
cp -R feather_m0/.cargo feather_m0/memory.x . - Add the BSP and any other required dependencies to
Cargo.toml:
[dependencies]
feather_m0 = "0.13"
panic-halt = "0.2"cargo buildshould create an ELF intarget/thumbv6m-none-eabi/debug/my_firmware
You'll need to add the proper compilation target prior to building:
$ # for samd11, samd21:
$ rustup target add thumbv6m-none-eabi
$ # for samd51, same51, same53, same54:
$ rustup target add thumbv7em-none-eabihfIf you'd like to build all the same things that the CI would build but on your local system, you can run:
$ ./build-all.pySee our wiki page about loading code onto the device.
