What are the libraries and teensy software version that were known to work? I’m suspicious of the V1.52 teensy libraries since the problem occurs using the recommended RA8875 library and latest

I am using the JackAl RA8875 library with the JackAl. I have another Teensy 3.6 on a breadboard that I connected to the LCD via the protection board instead of the JackAl which I was trying some of

Did you download our version of the display library? Jack, W8TEE

I would say that the issues are not serious enough for you to put yourselves in peril! HiHi! I've been working on installing the uBitx and JackAl board into the case before doing much more digging

Had the same issue...I abandoned the project and sold all..

Al and I are going to defy the Stay-In-Your-House-Or-Else edict and try to get together after the holiday to see if we can provide a fix to your problem. Jack, W8TEE

5"

In looking at my trace outputs it seems that my tx values are in the 400's and the ranges in the GetTouchCoordinates() code goes up to 750. Are the scale factors in the code set to a 5" display or a

No joy on the Jacks 7 reference (and variations thereof) other than in the JackAl.h file and appears commented out - no other instances found. In comparing the active vs. inactive code in

Very much the same as what I seen with the 7” only the performance was a bit worse.

As I recall, there are some sections in the code that have "Jacks 7" in them. Do a global search on that and see if they have any clues. (I can't get to my machine right now.) Jack, W8TEE

I looked at the video - virtually identical to what I'm seeing. Joe

Like Joe some of my touch points seem to be off even after a calibration. I make a few minute video showing the behavior in case it's helpful. Has anyone taken a video of their JackAl for comparison

I went back to ground zero following the library assignments in Jack's color coded post. It looks like calibration runs as intended, however, for some reason touches are not properly mapped to button

Let me talk with Al first... Jack, W8TEE

I have the same touch freeze issue on the 7” screen.

Jack, I’m local and have a 7” display that I’d be willing to let you guys use for revisiting this. Let me know if you’re interested.

OK - will do. Note that I'm using a 5" display but latest behavior definitely indicates what is recognized is shifted from what is actually touched so some sort of coordinate reversing is a

Al and I talked about this yesterday, and we (vaguely--we're old) remember the coordinate system was "reversed" on the 7" system. If you can, put in some Serial.print() statements in the calibration

Yup, they make sense and are in fact being stored. Now trying to see if the issue is in the RA8875 library. Curiously using the sumotoy 8875 library referenced in some JackAl literature produces a
