Not sure if I saw it on this mailing list before, but
I'm trying to determine if it's feasable to do
analog-digital conversion using a RC delay using
standard IO pins, and a counting routine in the
software.
I've searched google; didn't find anything good.
I'd like to use a 16F628 for my project as I only need
one ADC line!
thanks in advance for any help.
Brent
