I have recently ordered a Seeed TFT screen v2, because the first version was discontinued. When I received it, in less than ten minutes I had gotten all of the examples that came with it to work.
My ultimate aim in buying the tft shield was to make a small GUI where I could navigate around, and open files from the microsd card that I have.
To my distress, each of the GUI libraries made for the shield were made for version one, not version two. I had tried them, but none worked. The only documentation I see about v2 is on the SeeedStudio wiki for the product.
GUI for v1 of the tft shield: code,google,com/p/touch-screen-menu-library/
If anyone has made any buttons, menus etc for the shield, or has gotten a working gui on v2, please let me know.
