Thank you for the reply.

To answer your questions - I am using PicBasic Pro 3.0.7 evaluation version and I am running it in MicroCode Studio. I downloaded it because the original program was written in PicBasic. My experience with PicBasic is limited. I am working in assembly most of the time. I powered the PIC on both sides.

I agree with you that the PIC is not configured and this could be the cause of the problem. I contacted the author and asked him if the program and its HEX are complete and functional. He did not reply. His lack of reply strengthen my suspicion that the code is not complete.

Where you lost me is the code you proposed to include. Where does it go? Would you mind posting a complete PicBasic code as you propose to run to eliminate the problem with 16 blocks on the top line. I do not want to create new problems while I am trying to eliminate the old ones.

Thank you.
