The only catch I can think of is that you have to set RA5 to be an output--enabling PWM doesn't do that automatically. |

Practical application for Slave/Master switching. In this scenario, the PIC is a slave in a larger system. The system contains a computer running Windows, that is supposed to be the i2c master. How ... |

I had the same problem with the pic18f4550. To enter in mode debug, it needs the fuse #FUSES ICSP1.
Well that was huge. You nailed it! I'm not even sure if CCS would have been able to figure this ... |

I experienced the same problem recently. I currently have no time to chase it down, so all that I know is this:

Compilers are pretty smart these days. You should test a few of these operations and look at the code that is generated. Try divides and multiplies, try right and left shifts.

Cool. When I think GPS, Nixie tubes are the first thing I think of
I think your idea has merit. The conversions to and from ticks and dates are still messy, but at least people have been doing ... |

One more thing--the bit that enables the PSP is in the same TRIS E register as the customary TRIS bits. It's easy to change those extra bits when you think you're just setting the direction for E0/1/ ... |

This is going to be one of those “simple answer things” that I can't see. Nothing prints out, because you commented out all the printf's

Yes, it can be done with relays, and with circuits that replace relays.

"const" is a modifier, so we might need to see how you are using it. But for a general explanation, #define does not create anything in your program. It simply tells the compiler that any ... |

It would be rather hard to pin down a problem that was specific to that chip, unless someone has found it before. Meanwhile, there may be questions about the values you write to the EEPROM, so I'd su ... |
