I have a 12864F glcd with a toshiba controller. I have been unable to get the thing to work properly, and fear i may have damaged it somehow. I had it hooked up least week to a pic micro, and could only get it to display garbled text, and was trying to display lines, rectangles, etc. I decided to re-solder some wire to the connector, and attached those to single row headers to fit better into my breadboard.(the garbled text would chnge if i bumped the wires, and that prompted my decision to make sure the connections were decent) I don't think I got the glcd too hot when I did this, but I suppose anything is possible. Everything is hooked up correctly, and I even have a 10k pot connected between -V, +V and Vo for the contrast control, but nothing is being displayed. Could I have damaged the lcd? Is there any way to check if the lcd is damaged?
