I recently bought a 320x240 2.4" TFT with touch-screen in a Arduino-UNO shield format. I've bought three previously and one was a ILI9325 and other two were ST7781 controllers.
However, this new one returns the value 0 from the read-ID function. The eBay seller has no detailed information on the TFT module.
I saw a message several months ago that said that there were more than two different controllers being manufactured into UNO shields. But the message didn't specify what they could be if there was no response to code that reads the ID register for the ILI9325 or ST7781.
Might anyone know what other controllers are used with this form-factor?
