[oopic] Re: Finally got OOPIC working and LCD: Now new questions...

Sure, I understand the voltage divider but still don't see the limits
of the OOPIC line. Am I right to assume that the divider gets it in
the 0-5volt range and then through mathematical calculation the
correct value is achieved with the OOPIC?
