you've made several changes so could you please post the program and the printout ?
thanks |

TX and RX are situated at pinc6 and c7 respectively

| Hmm....you don't have the 'delay_ms(250);' just before the first print. |

One of the four PIC24 boards I maintain had an issue with unreliable serial output, and it ended up being caused by a timer ISR. I had to move it to a different timer and then the output worked fine.
I have no idea why that was, but left myself a TODO in the comments to look into it... some day.

Show your fuses.
How is the 64MHz generated????.
Show how the main code starts, and calls 'version'.
Did PUT make no difference at all?. |

More to the point, you really need to generate a basic test program that just
shows the issue. Simple main, and the code to call the version display.
Doing this then proves there isn't something hidden causing the issue as
Allen describes. Then post this. |
