Converts STM32CUBEMX Projects to bazel projects. This is acheived by making use of the generated .gpdsc files from stm32cubemx and outputing these in a bazel build file.

This project is in the early developement stage with fairly minimal but well tested functionality.

Requires a valid golang installation

go get -u github.com/gobuffalo/packr/v2/packr2
packr2 install github.com/silvergasp/CubeMxToBazel

wget https://github.com/silvergasp/CubeMxToBazel/releases/download/v1.0-beta.1/CubeMxToBazel-linux.tar.gz
tar xvzf CubeMxToBazel-linux.tar.gz
mv CubeMxToBazel ~/bin/

Select the "Other Toolchains (GPDSC)" configuration for your project in 'project>settings'.

Running the generator is as simple as changing directories into the project and running the converter

cd YOUR_PROJECT_PATH_HERE
$GOPATH/bin/CubeMxToBazel

The output of this is not neccesarily nice to look at, it is recommended to use bazel auto formatter for this.

# Install Autoformatter
go install github.com/bazelbuild/buildtools/buildifier
# Run formatter on generated build file
$GOPATH/bin/buildifier BUILD

Build all targets

cd YOUR_PROJECT_PATH_HERE
bazel build ... --crosstool_top=@bazel_arm_none//tools/arm_compiler:toolchain --cpu=armeabi-v7a

The resulting binary executable and binary libraries can be found under YOUR_PROJECT_PATH_HERE/bazel-bin. The resulting executable will be named YOUR_PROJECT_PATH_HERE/bazel-bin/main.

NOTE: On first run this project will download the official arm compiler, as such it is expected that you have a strong internet connection. This downloaded compiler will be cached and does not require re-downloading provided that the arm_none_bazel rule in WORKSPACE is not modified.

• [x] Converts generated *.gpdsc files from stm32cubemx into bazel BUILD files
• [x] Generates bazel WORKSPACE files
• [ ] Generate appropriate bazel compiler flags for; fpu, cpu, hosting specs, optimisations (Currently supports armv7e devices with hardware fpu)
• [x] Implement conditional file inclusion (e.g. conditional inclusion of assembly files based on the compiler)
