I recently bought a 3.5 inch tft lcd touchscreen module with touchscreen, 3.5" TFT LCD 480x320 Touch Screen HD Color Screen Module for UNO & MEGA 2560 Board with/Without Touch Panel with Touch pane : Amazon.ca: Industrial & Scientific
, and I calibrate the display and run the example Touch_shield_new from MCUFRIEND, and using the stylus to draw, the accuracy of the pixels drawn get noticebly worse when I move draw from the right side to the left side of the screen.
Any help is welcomed.
When you ran the calibration sketch, did you touch the upper left corner first? If you don't touch as far as it will detect, the calibration is thrown off. Same with the others. As close to the edge as possible.
Thanks for the response, but yeah I just tried that, and it still seems to be not working. My issue seems to be much like this Touch Screen Accuracy. [solved]
