So here is my codes;
I’ve got a full screen background image that is loaded into the LCD buffer once. Then many small squares are drawn on top. Touching one of these squares changes it’s state and a different colour is displayed.
Interaction with the grid is slow and the screen only updates a couple of times a second. Really only very small pieces of the screen need to be updated at any time but i’ve not worked out how to do that yet.
