I had the opportunity to try out MikroC just a few weeks ago. On the surface it looks pretty good, the IDE is nice but I found the help file to be lacking.
The other thing I hated was that the pro ... |

Thanks Guys,
The example code was a big help, seems like the #INT_IOC works well.
I like the flexibility of doing the pin assign which I think generally makes using ISR's alot easier and somewhat ... |

Thanks for the good explanation Ttelmah.
I think for the most part fast_io is better from the perspective that you
will save an instruction or two. I also like the idea of manual control.

I dont think you need to use a ISR or timer considering that your
code is running at 40Mhz.
Have you tried creating a couple of functions to handle the actual
led blinking instead of putting ever ... |

PCM, You are 100% right, I think I must of had a rough day or something
cant see the forest for the trees
So the PLL apears to be Ok.
Thanks for the sanity check

I tested in PCW both with ICD=True and release mode, results are the
same... 4x pll not working. On this particular part the pll should enable
for only 8Mhz and 16Mhz, resulting in a internal clock ... |
