2.8" Touchscreen edges not responsive.

by VioletTempest on Tue Dec 03, 2019 12:52 pm

I have been using the adafruit Feather M0 basic and wired the Adafruit 2.8" Color TFT Touchscreen Breakout v2 using the tutorial on the website. I loaded the graphics test and everything ran smoothly however I had an issue getting the breakouttouchpaint example to work. The edges of the screen do not seem to be responsive.

The only change I made to adjust the wiring to the Feather M0 was wire XP to digital pin 11. I noticed someone ran into the same issue on this thread however upon changed the calibration to:

Code: Select all | TOGGLE FULL SIZE
#define TS_MINX 150
#define TS_MINY 130
#define TS_MAXX 3800
#define TS_MAXY 4000

the screen becomes unresponsive entirely. Does anyone have a solution for this or have a possible fix? Will getting the STMPE touchscreen controller help at all?

ALSO: with the Serial print of the location of the x and y coords uncommented it doesn't appear to use the full screen. When trying to touch 0,0 it usually prints 55,55.
