Im sorry I can't really give you an FPS Brad, it depends on the render time it takes within the Graphic subroutines and what you are sending out to the display.. But it is pretty quick!.
brad wrote:How many colors can you get from it?
The shield we have used is one from IteadStudio
2.4 TFT Display. It has just over 262K of colors.
We have a routine abit like - "SetPenColor(255, 255, 255)" within each parameter you can enter a value between 0-255, which represents (RED, GREEN, BLUE).

I have some example code below, but all the examples including the code will be released soon.
Code: Select all
