    With a T4.1 if it is not liking your program and crashes... One of the things to try then is to reset it to the default program. You can do that by holding in the program button for about 20+ seconds, until yo see...

    The Teensy log only shows stuff about about the log... Note: Serial output at the start of a sketch can often be faster than the Serial system on a PC can be initialized... That is the USB is part of the Teensy...

    Looks like you have tested most of the obvious things. Hopefully once you can ring out the different pins, to verify everything works, the issue will show up. Likewise I would check with a voltmeter what voltage is...

    I assume you are trying it with the same display and the like. If not I would probably try with a different one to make sure it is not a display issue. Like are they setup to be powered the same? I ordered mine...

    Hopefully someone who uses these a lot will be able to give you a more complete answer. At one point I played around with my own carrier board, that I could use with the RA8875 and some with the RA8876 boards... It...

    Sounds like a good idea. As you mentioned, at some point it might also be good to extract the GPIO/DMA stuff and optionally keep or not in own source file(s). Maybe also the FlexIO stuff to it's own file(s). Maybe...

    I was sort-of kidding, but thought I would try a few things and see what happens with flexIO. Currently I don't have a total set of correction code in the flexIO stuff. That is I request from the specified timer,...
