hi Oleg,
thanks for ur advice. I meant 32 columns not 32 characters.
As Benjamin guessed, this is a personal project and is a first for me in programmable electronics.
I haven't produced my schematic diag. yet and as i don't know how to produce a PCB, I intend to use a Vero board (that is what i have always used for my projects till now.
About the program and explanation, could U shed more light on it? I couldn't completely understand it.

Thanks,
Ehigie
