HAL for the Vorago VA108xx MCU family
This repository contains the Hardware Abstraction Layer (HAL), which is an additional hardware abstraction on top of the peripheral access API.
It is the result of reading the datasheet for the device and encoding a type-safe layer over the raw PAC. This crate also implements traits specified by the embedded-hal project, making it compatible with various drivers in the embedded rust ecosystem.
In contrats to other HAL implementations, there is only one chip variant available here so there is no need to pass the chip variant as a feature.
The first way to use this HAL will probably be with the REB1 development board. The BSP provided for this board also contains instructions how to flash the board.
Building an application requires the
thumbv6m-none-eabi cross-compiler toolchain.
If you have not installed it yet, you can do so with
rustup target add thumbv6m-none-eabi
After that, you can use
cargo build to build the development version of the crate.
If you have not done this yet, it is recommended to read some of the excellent resources available to learn Rust:
Some examples, which are not specific to a particular board were provided as well. You can build the timer example with
cargo build --example timer-ticks
Setting up your own binary crate
If you have a custom board, you might be interested in setting up a new binary crate for your project. These steps aim to provide a complete list to get a binary crate working to flash your custom board.
The hello world of embedded development is usually to blinky a LED. This example is contained within the examples folder.
Set up your Rust cross-compiler if you have not done so yet. See more in the build chapter
Create a new binary crate with
To ensure that
cargo buildcross-compiles, it is recommended to create a
.cargo/config.tomlfile. A sample

Flashing the board might work differently for different boards and there is usually more than one way. You can find example instructions for the REB1 development board here.
