Unknown driver chip 9393

by pigman on Fri Jun 01, 2012 12:28 am

Hey, I have a adafruit 2.8" touch lcd thino and I broke the screen :( so I bought a replacement lcd from ebay that stated the correct driver and pinout and whatnot and installed it onto the arduino shield board. Its an ILI9325 chip LCD with the touch stuff here is the link and when that failed I got one from AliExpress that also gave the same driver chip 9393, when I hard code the driver chip ID into the program here

Code: Select all | TOGGLE FULL SIZE
Serial.print("Unknown driver chip ");
    Serial.println(identifier, HEX);
    //while (1);

I get no joy :( Can someone point me in the right direction with the code or perhaps somewhere I can get a replacement LCD panel? That might work :)

your best option is to email the place you purchased those TFTs and ask them for the programming help, we can only guarantee that our code and shield works with the TFTs we sell
