16f886 and LCDOUT

[rsocor01]

Hi Robert.

The LCD is blank which leads me to think i'm not initializing it. I'm using a 20k variable contrast resistor. I made the change IOCB.0 =0 to IOCB = 0 with no change. I will keep experimenting and post my results.
Thanks again.

Hmmm, I haven't worked with these LCD displays in a while, but I think 20k is too high. The way I do it is by using a 10k pot and I play with it (change values from 0 to 10k) to find the optimum value. Give it a try and let us know....

Thanks Robert. It is my contrast setting. The LCD works and I'm a bit more educated regarding the special function registers of a 16f886. I did check the setting on an earlier date but had no idea that the supply voltage would be so low. 800mv on pin 3 displays fine. I didn't adjust that far down until your suggestion. Thanks again and thanks for everyones input.
