Thanks Steve,
I am running the PBP 2.50B version: is the Darrel include applicable to my pbp version ?
If not, what could I do ? Any possible modification to the program ?

I can not advise you on this. Is there a pressing reason you want to use this LCD? There are LCDs that are easier to use and this one just looks like hard work to me.

Steve,
Thanks.
I have no more pins available on the pic and I have this LCD on my hands.
Anyway, what LCD ( 20x4) with serial interface could you suggest to me ? I could try to get one.
