First time I saw the graphics capabilities of FT800 was on the Gameduino2. From then I’ve wondered if FT800 could be used as graphics controller in my weatherstation project.
Due to limited resolution it could only be used for LCDs up to 5″. Since then, the FT81x series of controllers have been released. They support higher resolutions and allows for typical 7″ displays. In the meantime I’ve also experimented with capacitive touch panels. I find them so much better that the resistive ones.
