This guide explains how to setup an embedded Rust development environment for the Numworks n0110 calculator.
To develop software in Rust you need the Rust toolchain which can be installed using rustup using the instructions at rust-lang.org/tools/install.
To build for STM32 we need the GNU Arm Embedded Toolchain, you can either install it using a package manager or download the binaries directly from the developer.arm.com and then add it to your path.
Use the following instructions to use your operating system's package manager or if your OS isn't listed use the built in search function to find it.
sudo apt-get install gcc-arm-none-eabiInstall Homebrew then run the following:
brew tap osx-cross/arm
brew install arm-gcc-binIf you don't have an STLink probe you will need to flash the calculator using DFU (you'll still need this to test your changes even if you have an STLink). You can get this by following the instructions on the dfu-util homepage.
RustWorks and some related projects use
cargo-make to make flashing
easier and
cargo-binutils to convert
the output of cargo build into raw binaries. Install them using the following
commands:
cargo install cargo-binutils
cargo install cargo-makeWe also need to add the thumbv7em-none-eabi target to Rust and install the
Rust LLVM tools preview:
rustup target add thumbv7em-none-eabihf
rustup component add llvm-tools-previewIf you have an STLink probe you can also install probe-run, cargo-embed and
cargo-flash to make flashing and debugging easier:
cargo install probe-run
cargo install cargo-embed
cargo install cargo-flash
