I have a 5” 800x480 SSD1963 display with a resistive touch screen attached to a XPT2046 chip. The shield is attached to an Arduino Mega.
The display came with UTFT and UTOUCH . I have graded to URTouch but it has the same problem. The driver board was originally set up for software SPI and has worked fine for years. I recently changed the jumpers to Hardware SPI which changed the MOSI, MISO and SCLK pins to the standard Arduino Mega pins and this is when the problem started.
XPT2046_Touch and TFT_Touch both work fine with the new pin configuration (they wouldn’t work with the jumpers set to Software SPI)
I can only clear the problem by disconnecting the USB cable then it will work again for 2 to 3 presses then hang again. I did change the jumpers back to software SPI and it was fine again.
Has anyone seen this problem?
Edit
removed Adafruit_ TOUCHScreen and XPT2046 question
