I am going to try this today thanks.
I am following John Iovine,s book, he usesa F84a pic. He always uses the portB by default, I wanted to try using port A , but on a F88.
Also I was reading the command CMCON=7 meaning th three first bit are set to one. When I read the legend it says 1 is for Setting th bit, I would of first thought setting would be for setting for comparator mode.
