This is my first post in arduino community, i received today a TFT 3.5 Touchscreen, and i started by downloading libraries like mcufriend and adafruit gfx and lcd.
The lcd itself is working perfect but the touchscreen is in unknown condition?!
Can anyone help me and how to calibrate, because i still cant understand how it does that, and its giving back id something and here when i try to calibrate.
21:00:14.782 -> TouchScreen.h GFX Calibration 21:00:14.782 -> Making all control and bus pins INPUT_PULLUP 21:00:14.850 -> Typical 30k Analog pullup with corresponding pin 21:00:14.885 -> would read low when digital is written LOW 21:00:14.954 -> e.g. reads ~25 for 300R X direction 21:00:14.988 -> e.g. reads ~30 for 500R Y direction 21:00:15.023 -> 21:00:15.023 -> MISSING TOUCHSCREEN 21:00:15.532 -> ID = 0x6814
