* format: Strip trailing whitespaces
We want to get rid of trailing whitespaces completly as they make just git
noice. Much better to start using automated tools to get rid of them once and
not getting them back again. This way git history will be cleaner and review
easier.
Commit was generated with:
pre-commit run --all-files trailing-whitespace
* format: Files should have exactly one new line end of them
It is good practice that every file has one new line. It is not now days so
mandatory but it also is not nice if file has lot of newlines end of it. We will
use pre-commit which takes automatically care about this so let's fix all.
Commit was generated with:
pre-commit run --all-files end-of-file-fixer
* format: Convert tabs to spaces
Project mostly use spaces over tabs. When mixing tabs and spaces this usually
makes formatting issues and also when changing those in commits it will make lot
of git noise. We will force spaces most of the time and use pre-commit to fix.

pre-commit run --all-files remove-tabs

Building this Project
IAR EWARM Project
There is an IAR EWARM project bacnet.ewp that can be used to build the project.
GNU Makefile
There is a GNU Makefile that uses arm-none-eabi-gcc to build the project. It also includes recipes for openocd or stlink, and gdb or ddd for debugging.
This is used in the continuous integration pipeline to validate the build is not broken. The Makefile is called from an Ubuntu image container after installing the necesary tools:
sudo apt-get update -qq
sudo apt-get install -qq build-essential
sudo apt-get install -qq gcc-arm-none-eabi
sudo apt-get install -qq libnewlib-arm-none-eabi
For debugging, install these tools:
sudo apt-get update -qq
sudo apt-get install -qq openocd gdb-multiarch
CMake & Visual Studio Code
There is a CMakeLists.txt file that enables building the project with the tools that CMake can find. It is useful under Visual Studio Code editor with the CMake Tools extension for quickly configuring the build environment, choosing a cross-compiler, and building.
For Visual Studio Code debugging, add the Cortex-Debug extension, and configure its settings for the specific OS and path of the tools. For Windows using MinGW64:
"cortex-debug.armToolchainPath.windows": "C:/msys64/mingw64/bin",
"cortex-debug.gdbPath.windows": "C:/msys64/mingw64/bin/gdb-multiarch.exe",
"cortex-debug.objdumpPath.windows": "C:/msys64/mingw64/bin/objdump.exe",
"cortex-debug.openocdPath.windows": "C:/msys64/mingw64/bin/openocd.exe",
To add the build and debug tools to MinGW64 environment:
pacman --noconfirm -S mingw-w64-x86_64-arm-none-eabi-gcc
pacman --noconfirm -S mingw-w64-x86_64-openocd
pacman --noconfirm -S mingw-w64-x86_64-gdb-multiarch
