Thanks for the look at.
I am very interested in the test/play program. Is that on the ESP32 and SPI?
By the way, for my application, I had to change to the MEGA, as with the UNO, there were no digital I/O pins availible.

The attached program is an attempt to talk to a LCD / Touchscreen with an UNO.
While it simutales OK, I am not getting any response after compiling to the target. I suspect that there are some parameters within the board properties that are incorerect.
