STM32 development and debugging using VSCode
ST provide an IDE (Integrated Development Environment) for STM32 development. As a beginner's environment to learn embedded programming on STM32 MCUs this IDE is not half bad.
Prerequisites
This example is developed on a standard Debian desktop system. On an Ubuntu system it should be almost the same.
Toolchain
The toolchain refers to the compiler and the tools to manipulate binary images. On Debian those are available in the standard repository:
$ sudo apt install gcc-arm-none-eabi binutils-arm-none-eabi
GNU Debugger (GDB)
The GNU Debugger (GDB) is also available:
$ sudo apt install gdb-multiarch
OpenOCD
To communicate with the actual STM32 MCU a JTAG/SWD tool is necessary. Fortunately the standard OpenOCD in Debian support STM32/ST-Link:
$ sudo apt install openocd
STM32CubeMX
STM32CubeMX can be downloaded directly from [ST's Website].
