Touch panel intermittent

Open Jim-bee opened this issue 4 years ago • 0 comments

I am using a buy display 2.8" SPI interface for the screen and using your tft_touch library to run the touch panel. This is attached to an Adafruit GrandCentral M4 board running at 120MHz. The issue I am seeing is the touch panel works most of the time but some times it will not recognize a button touch. Seems to lock up usually / mostly after reboot or sending firmware to the board. Could this be a timing issue with the M4's faster clock talking to the XPT2046 chip?

Thanks, Jim
