Sorry.
Remove the T2_INTERNAL constant. The correct setup_timer_2() calls should be :
setup_timer_2(T2_DISABLED|T2_DIV_BY_1,29,1);
and
setup_timer_2(T2_DIV_BY_1,29,1); |

I'm trying to get the PWMs working with Timer4 on a PIC18F6720 instead of Timer2. Here's my problem...
If I use the following code snippet, I cannot get PWM5 to run

Not quite sure what a character syntax error is, but the definitions you made for the channels in binary look a little off. I was under the impression that binary numbers were written like 0b11010101 ... |

Thanks for responding.
It tried what you said, by adding those lines, and putting a tx_on() before my transmission routine and tx_break() at the end of the routine as well as in main(), but it didn ... |

In case you don't know, the only real difference between IEEE-754 and the Microchip floating point numbers is where the sign bit resides. Here is some code I wrote to do the conversion, though it [spam] ... |

It might help to know what type of timing error you can tolerate. If you are reading every hour for 1000 hours, then a couple of seconds either way may not make a difference. If that's the key, you ... |

I finally seem to have found a solution to my problem. It seems if I add a typecast for RawValue to a float in the third line from the end, the calculation for Correct.fValue. This line would then l ... |

If I understand correctly, you want to configure the MAX3100. I've used the MAX3110 before (close to the same part).
Note that spi_write() only uses 8-bit ints, so you need multiple writes to get ... |
