I got hold of a LCD display that I would like to use for a prodject im doing, the problem is I cant find any information on it, Ive done a continuity test on the terminals and have found that term 3 is ground and terns a/k are for the backlight but other then that im stuck can anyone help?
No, to get any characters you need to feed it correctly and exactly, there are plenty of examples about - including my PIC tutorials. You can download a good article (actually a two part series) from the EPE website.
I believe that any pic, having enough i/o pins will do. Not sure about 16f84a, but perhaps. E.g. At89s2051 can do as a microcintroller, having 2 bidirectional i/o ports - 1 pin (15 i/o pins in total).
Yep its a standard pinout 1-14....with 15 and 16 being the LED backlight power. Looks like theres already two resistors in series with it, so I suspect is the usual 4.2V @ 150 mA.
