Simple answer, NXP has no accessible AGND on these chips so Teensy 4.x can’t have one. While the analog inputs aren’t as ‘good’ as prior models they should more than suffice for 7-bit MIDI with little to no issue.
I wasn’t aware the other 4 buffers were broken, good to know in the future though. Sounds like you’re more familiar with it than I am so I can only help so much.
However I don’t think the PXP rotation is going to...
I’m curious, since you are using FlexIO, if it wouldn’t be beneficial to make use of its buffers rather than maintaining 2 complete buffers for the screen. Since each FlexIO has 8 32 bit shift registers it can buffer 16...
1. In the context of rotation, logically I believe that makes sense that it’s clipped to 320x320, though I understand that doesn’t really solve your problem when transferring to the screen. Now that I think about it...
Truthfully I haven’t done much with this since making the library, very little even at that, so my memory of it isn’t the best.
1. That sounds about right, all the functions just change placeholder variables then call...
I only have cursory experience with this, but it really depends on the situation wether you need the extra framebuffers or not. I feel like most people generally redraw the entire framebuffer for each update so there is...
I’m a little at a loss for why the rotation is needed in software, don’t these type of displays usually have a built in rotation to match the buffer you send it? I’ll admit I’ve never used one of the ILI type displays...
