Keep reading, especially the datasheet for the appropriate PIC (I'm thinking either the PIC10F322 or the PIC12F1572).So neither of you have a link that shows a PIC IN A CIRCUIT, and text that treats the programming and shows the IO of the chip in context? I am getting CLSE to the most rudimentary grasp of these, but would like to see one actually doing something that looks like "analog". Just the way my brain learns.
Also, the user documentation for the XC8 C compiler (or the MPASM assembler), the MPLAB-X integrated development environment (IDE), and the PICKIT 3 programmer/debugger tool.
Meanwhile, I'll try to whip up a schematic for you and post it, probably Monday or Tuesday.
