Greetings All,

I have been trying to get the 16 x 2 Serial LCD Display from Renolds to work with my PIC16F628A so that I can display sensible output which would help with my other experiments.

I finally got it to work on a Basic Stamp BS2p (major success). Code at bottom of message - as you can see it is pretty basic at this stage but it took me a long time to get this working.

The question is how do I replicate this on my PIC with a 4MHz Oscillator.

I tried the second lot of code at bottom of message, and got funny characters appearing so I figure I am pretty close just an issue with the baud rate.

I also found if I followed other examples (and in the documentation) and put in a N9600 I got a BAD EXPRESSION ERROR. What is that all about.

Thanks in advance.

Cheers Bruce
