I expect the UNO to place data into the SD card, and then the TFT controller would use it to construct the output for the display. Is that the way it works?Typically the images would be constructed offline on a PC. The UNO would then copy images from the SD card to the TFT.
Ahhhh, I see. Pitty that I have to feed the TFT controller, but such is life.
