Export STM32 CubeMX pin assignments to matching symbols in a KiCad schematic

This tool reads a CubeMX .ioc file, constructs pin labels and applies those to matching MCU symbols in the given KiCad schematic file.

Usage

./cubemx2kicad.js STM32CubeMX_file.ioc KiCad_schematic_file.kicad_sch

Installation

Just clone the repo, beyond Node.JS no dependencies.

Some points of attention

• CubeMX can stay open during this, but the KiCad schematic editor should be closed and re-opened after
• Use 'user label' in CubeMX for best experience
• The backup and log functions need to be disbled in the source
• This messes up / does not work with alternate pin functions in KiCad, beware.
• The KiCad ERC will complain that the MCU symbol will no longer match the library.
• The KiCad 'parser' is extremely simplistic and doesn't respect the s-expression scoping. It works for what KiCad saves, but is probably fragile when using other exporters.
