White screen on Adafruit 2.8" TFT Touch Shield for Arduino v2

Other Hardware Displays
1

I have been using a

  • Arduino Uno WiFi R2
  • Adafruit 2.8" TFT Touch Shield for Arduino V2

I have tried multiple libraries like

  • ILI9341 library: which displays an output in the serial monitor, however i do not see any image from when trying the graphics test.
  • TFTLCD Library: which results in a compilation error "#error "Board type unsupported / not recognized""

I am unsure how to proceed or what drivers to use.

Try this library and see how it goes.

I have run the diagnose TFT support file, which gives me

MCUFRIEND_kbv version: 3.0.0

Probably a write-only Mega2560 Shield
Try to force ID = 0x9481

PORTRAIT is 320 x 480

Run the examples/graphictest_kbv sketch
All colours, text, directions, rotations, scrolls
should work. If there is a problem, make notes on paper
Post accurate description of problem to Forum
Or post a link to a video (or photos)

The graphictest_kbv sketch gives the following output:
Serial took 0ms to start

ID = 0xD3D3

The screen stays white. The code by default forces the 0x9481.

I have switched to the Arduino Uno R3 instead of Arduino Uno Wifi R2 and now the screen is working. It may have been an issue with compatability
