Re: 16F84 HELP!!!

Sparks,

I think you need to take a step back and apologize to Alan, Fowler, Phil and Brian. The perceived (at least by me) attitude of your posts is childish and ignorant. Concerning the latter perception, I’m betting that you are not or you would not be attempting a project like this. Concerning the former perception, the teen angst bit may work with your parents and school teachers as they have little choice than to put up with it. In this forum, you will find it much more efficient to conduct yourself as an adult and make an effort to communicate better. All any of us are doing here is trying to help you out…

Now I’ll get off my soapbox and get on to your problem.

There is nothing wrong in the programming circuit proposed in Mr. Peno’s site and there is nothing wrong in using IC-PROG. It appears that you have some problem understanding the mechanisms involved in embedded microprocessors. That’s OK. We all have to start somewhere…

Instead of trying to explain it all at once, I’m going to direct you to a site at the University of Texas:

http://www.ece.utexas.edu/handson/robocar/

In this project, you will find that they use the same JDM compatible programming circuit (http://www.ece.utexas.edu/handson/ro...programmer.gif) as Mr. Pino. They have also provided an excellent piece of “test” code (http://www.ece.utexas.edu/handson/ro...code/TEST1.HEX) and a test circuit (http://www.ece.utexas.edu/handson/ro...picledtest.gif) to verify programming. They have also included detailed step-by-step instructions on the programming process (http://www.ece.utexas.edu/handson/ro...programmer.htm)*.

After you have succeeded in getting the LED to flash, you should look at TEST1.ASM and see how it was done.

Lastly, you should now try to assemble TEST1.ASM into your own TEST1.HEX using MPLAB (or whatever tool you are using) and verify that it works in your circuit as well.

If at any point in this process, you hit a snag, please post here and ask for help. Just remember to try and put yourself in our shoes when you proofread your post. Have you given us all relevant information and is it easily understood?

Best of Luck,

Mike

Post Script: You should try a private message to Brandon Martus if you continue to have a problem with the spell check routine. I’m using Firefox 1.06 under Windows XP SP2 and I have no problems with it.
