Hi,
You have one TFT shield for Arduino MEGA or Arduino Due. It uses a 16bit parallel bus for the display. It doesn't match on a UNO R3 or UNO R4.
I don't see an easy solution to use it with an Arduino R4, because of too many port pins needed.
You have one TFT shield for Arduino UNO. It uses an 8bit parallel bus for the display. It perfectly matches with Arduino UNO R3 or Arduino UNO R4.
There is one solution to use it with MCUFriend_kbv, by replacing one header file for port pin driving.
And there is a solution to use it with Arduino_GFX using my fork of this library.
