Vex Swift

This repository is an experiment with using Swift to develop on the VEX V5 platform.

Environment setup

Install Swiftly, then run swiftly install in this directory. Swiftly will automatically pick up the .swift-version and use the right compiler in this directory.

Install swift-v5 from the vexide GitHub, then run swift v5 install in this directory. This will install the ARM Toolchain for Embedded. Once the download finishes, swift-v5 will tell you where it installed the toolchain. Symlink that directory to ./llvm-toolchain.

The path will be different on different operating systems, but here is what it looks like on macOS:

ln -s "$HOME/Library/Application Support/dev.vexide.swift-v5/llvm-toolchains/20.1.0" llvm-toolchain

Build command

swift build -c release --triple armv7-none-none-eabi --toolset toolset.json

The ELF output is located at: ./.build/release/VexSwiftApp.

Big one-liner that does all the things™

swift build -c release --triple armv7-none-none-eabi --toolset toolset.json && llvm-objcopy -O binary ./.build/release/VexSwiftApp ./.build/release/VexSwiftApp.bin && cargo v5 run --file=./.build/release/VexSwiftApp.bin --slot=1
