same screen mode is not very helpful. (unless you quote message # )Please post link to actual display e.g. Ebay sale.David.
That is a Blue 3.5 inch Uno Shield. Usually contains ILI9481 or ILI9486.Runs well with Uno. Runs on a Mega2560 but is slower than Uno.Install Adafruit_GFX library with the Library Manager.Install MCUFRIEND_kbv library with the Library Manager.It has a resistive Touch Screen that shares pins with the TFT.Install TouchScreen library from Adafruit with the Library Manager.Most Arduino graphics libraries use Adafruit_GFX style methods.So it is fairly easy to adapt programs for GLCD, OLED, TFT from Adafruit, MarekBuriak, Bodmer, ...I suggest that you start with all the examples that come with your library.Or just quote an example from a different library and ask if possible to "port" to the library you are using.Always write new programs in the native GFX style.David.
