Scampy,

That is interesting and a part of this PIC I don't fully understand. I've used PIC's with Internal OSC before, but quite a while ago and I don't remember being this confused about it.

It seems unclear to me in the datasheet what frequency the internal OSC runs at and if any external components are required. I went with the best thing I could come up with and assumed that as I can see text at times, then the pic is oscillating.
I did try DEFINE OSC 4 at the top earlier, but the problem still occurred.
