problems with parallel LCD

[Darrel Taylor]

Since you're using PORTA. You probably just need to disable the analog functions (A/D and Comparators).

Which PIC are you using?

I'm using the 16F628.
I tried adding:
Symbol cmcon = $1F
Poke cmcon, 7
(is this what you were talking about?)
and nothing changed. Yeah, I don't really know what else to do.

Thanks

Something I always do...no matter how sure of myself I am...
I connect a heartbeat LED. Just set aside a pin to do nothing more than flash an LED.
The absolute first thing I do. You can verify and check sooooo many things with just that little bitty LED.
Also, you might want to increase that pause 200 to pause 1000 or 2000 and see what happens.

Hello Mr. Brown,
I know PBP and PB are somewhat different, in PBP the statement would be just<br>CMCON = 7

Hi, I tried your suggestions and unfortunately my LCD still isn't working. I think I'll just order another one sometime and test it out. If anyone has an idea let me know.

Thanks

Are you seeing any blocks on the screen or anything at all? Remember to try viewing the LCD at various angles...

[Brown]

Yeah, I'm not seeing anything at all. I remember now that it's a transreflective LCD, so maybe something's getting messed up with its light adjustment stuff. Anyways, just a thought...
