I’m new to the Arduino. I have an Arduino Uno R3 with the IDE 1.8.1 and a 2.8" TFT LCD from ebay with identical pins as the www.mcufriend.com 2.8" TFT LCD.
I’m able to write graphics code to the shield successfully.
Now I’m trying to run the Adafruit_TFTLCD\examples\tftpaint2 sketch (code is attached) but the touch doesn’t seem to work.
When I run the sketch it shows it’s the 9431 controller and it outputs 8 boxes across the top of the shield but it does not respond to touch.
Is there any diagnostic code I could add that would tell me if the screen is good?
