Hi,
I have a problem that has been giving me the slip for three or four days. I have tried everything I can find, most too complicated for my simple task.
I have a 3.5 TFT / Touch / SD card shield, with pins directly onto the uno. It looks okay but I would like to place a file in the root of the SD called "Alien8.bmp" as the background of the display. I have tried to attach an ebay picture the same as my shield.
I just can't find a way to achieve this.. Please can anyone help this old git!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It looks okay but I would like to place a file in the root of the SD called "Alien8.bmp" as the background of the display. I have tried to attach an ebay picture the same as my shield.
I just can't find a way to achieve this.. Please can anyone help this old git!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
