Nokia COLOR LCD PicBasicPro 2.50a example code

[jchandir]

I just bought a Nokia Color knock-off lcd from sparkfun. I am using a pic 18f452 at 4Mhz and pic basic pro compiler and the LCD has a green board (Epson). So far I got it to initialize and all I am trying to do is clear the LCD since its all random pixels when the screen turns on. I have it running in 12bit mode, and I can select every pixel and make them white.

The problem is when I choose any other color like green or red or
anything other then $FFF. The screen begins the clearing process but it
gets stuck mid way threw at different locations every time.. Its like the LCD freezes. I have read the forums and did lots of searching and heard of someone else with the same problem but no one knew how to fix it. Also, when i change the OSC to 20 or 40 Mhz, the lcd never works. I hook up everything to an oscilloscope and I can see the data, but the LCD dosn't even blink.. Could there be something wrong with the controller? Or am I missing something. I was wondering if someone could shine some light on this problem. Thank you.

Try feeding data to it a little slower, maybe you are overrunning it's input buffer.

I am using a 4 mhz xtal, its painfully slow already.. I don't think speed is the problem. I am using shiftout command and sending a C/D bit and then the data. Any other suggestions? I have even tried Daves color lcd program, compiled it, and it works really weird. The colors are not right in 8 bit mode, and the text comes up as just small little lines where the letters should be. I just bough two of these lcds and both do the same thing. Is it possible that epson came out with a new controller. I am using the data sheet that sparkfun supplys and it works in 12 bit mode, besides the freezing but 8 bit sucks. I am also using a resistor divider circuit to step it down from 5v to 3.3.
