PIC's are new to me full stop. I am on a steep learning curve with regard to
both the architecture and the programming languages. It has been many years
since I last designed an electronic circuit from scratch too and this is my
first circuit using an embedded processor so I am rusty in that area too. Add to
that the fact that I became disabled with a medical condition a few years ago
that leaves me with 'brain fogs' and you can see that I have quite a challenge
in front of me (in fact I am pleased that I have been able to get this far
before ginding to a complete stop).

The problem I found was that I was having difficulty grasping the ASM language
(it seemed totally confusing despite lots of research) but I could understand
how the basic programs were put together.

I may have to delve into the .asm file and see if I can spot anything in there.

Thanks for your suggestions.
