I remember we had to use either VSC or PyCharm (can't remember which) in conjunction with Thonny to get a workable process. Again, it has been a few years and we switched the product to STM32, forgive me if I don't recall details. I think the issue was that debug communications did not work unless we used Thonny (which nobody was interested in touching for anything other than a downloader).

BTW, that project used MicroPython. That did not go very well. We had to replace portions of the code with ARM assembler for performance reasons, we simply could not get efficient communications with MicroPython.

Thanks again. Very much a fan. I mentored our local FRC robotics high school team for a few years. Lots of learning by the kids using your products. Incredibly valuable.
