Reviving the topic.
I�ve tried to use the Neutone�s Code in a PIC18F452 with PCH 2.234, and I use the ModBusView (www.oceancontrols.com.au) to try to communicate to my PC.
I used th ... |

Thanks, Mike, but it didn�t work!
It looks like the pic didn�t run, I put a BEEP on first line, but nothing happens.
Any idea? |

1. Are you running the internal oscillator?
No, I use an external clock. But It was working fine on 16F876, so, I don�t think it is a problem.
2. Make sure you ensure that your comparator ... |

Well, I found the light.
I thought the CCS could be missconfigurating the priority bits for any reason and - bingo. The priorities were wrong.
So I configurated it by myself.

I clear the flag in each interruption.
But bfemmel, look at it and see if it isn�t strange.
The program goes to line 0008 when the timer1 overflows.
But the timer1 is a low priority interrupt ... |

Well, I think it can be a bug.
The CCS generated the following code:
0000 EF04 GOTO 0x5c08
0008 EF5E GOTO 0xbc
000C 0000 NOP
000E 0000 NOP
0010 0000 ... |

Well, actually I don�t have a interrupt handler. So I relly need?
It would be so nice if this "HIGH" just modify the priority, and let the athers things untouched. ... |

Well, the HIGH is a recent implementation. Looks very similar to FAST, buts the readme says that a high interruption can stop another interruption (such a FAS ... |
