Time to give something back to the community. I have cleaned up the code and the repo and made it public now. It can be found here:
https://github.com/Igitigit2/SimpleCanLib.git
Support for STM32 and ESP32 is available and I added an extensive readme.md. Probably there is still a lot to be improved in the documentation, but for now it must suffice. I hope I won’t mess up things simce I am always fighting wit github, branches and pull requests…
Anyway, have fun with it and let me know if something doesn’t work as expected!
