IMHO, all of these questions are valid except for the one asking about why he is using such an old micro. First, it has nothing to do with the request. Second, if you write a program for the F84, you can port it to other micros in the PIC family with little to no changes. And third, who care? What possible difference could it make why he is using that particular part. He didn't ask if he was using the right part or if it was a current part, He was asking for help with programming a counter. Don't take this the wrong way. I'm not trying to start a flame war.=20 I'm just pointing out that a question was asked inquiring about a fact that has nothing to do with the request the OP made.
