gabs4 / stm32-cmake

Base project for STM32 using CMake

STM32 CMake project template

Dependencies

git
gnumake
cmake
gcc-arm-embedded
clang-tools (optional)

I would recommend gcc-10.3.y for latest C++20 features. Versions 9.x.y will still do C++20 but with a limited feature set. If you have newer, then go for it.

You can download arm-none-eabi toolchain from website. It is universal for most distros. If your distribution carries it, install it with that, but mind the version and compatability.

Fedora 35 comes with latest gcc-11 with these packages:

arm-none-eabi-gcc-cs
arm-none-eabi-gcc-cs-c++
arm-none-eabi-newlib

Fedora does not have gdb in its packages, so you might want to download that separately.

On ubuntu 20.04 LTS you can install all with just one package, but comes with older gcc-9, which does not support all the C++20 features:

gcc-arm-none-eabi

Arch has gcc-11 and you can install it with following packages:

arm-none-eabi-gcc
arm-none-eabi-newlib

optional:
arm-none-eabi-gdb (debugger)
arm-none-eabi-binutils (utilities)

NOTE. If your cmake fails to "compile a simple test program" while running the example, then you might not have newlib installed (one of the errors I have encountered). In the examples above, fedora and arch carry the package separately, but ubuntu has it all in one.

Example

You can utilize everything in root of the repository to build an example project.

Workflow

Output files will be located, by default, in build. You can change that with BUILD_DIR parameter in the Makefile.

Just run cmake:

make cmake

Run cmake and build:

make -j<number of threads>

Clean:

make clean

Format all source files:

make format -j<number of threads>
