• Thanks Gordon,
    Thanks for the confirmation and the clear options. I’ve been doing some more googling and checked out the libraries and stm32 reference docs. I think it’s possible but I have to say it looks incredible complex.
    On a general point this https://youtu.be/4FOkJLp_PUw

    is a great youtube tutorial with stm32 that shows the logic analyser techniques (and effort ) it might take to debug such a development.
