| Why is THIS important?? |

Ok, i am ripping out my hair because no matter what CCS says, the data sheet doesn't match up.
I've used this chip successfully before, on CCS 4.114
SAME code, 4.130 it works yet the system keeps rebooting or restarting as though Watch dog is in use!
CCS 4.114, it works FINE, ONLY when i have a call to reset_cpu() in a FUNCTION that is NEVER used! or setup as interrupted!??

I'd have to dump out the listings and compare the two.
It's not uncommon that a fuse(maybe WDT) is being set/reset to the wrong condition for a different compiler version which we can't tell by just the program.

You have not got a UART selected in your #use RS232. Surprised it compiles. The line above 'remmed' out, does have the UART selected, but lacks 'ERRORS'.
I'd suspect you were compiling with this line before.

If it's re-booting, get the PIC to tell you what is causing the re-boot.
Attack the problem head on, don't flounder in the dark.

the line
//#use rs232(UART1, baud=57600,parity=N,bits=8,stream=PORT1)
#use rs232(STREAM=UART1,baud=57600, parity=N,bits=8,ERRORS)
the one remmed out, didn't compile :( it was strange...
but why.. would a function that is NOT called, cause the chip to work?? |

it just fixed it self! ok, now i AM confused!
the timing seems abit off though
12M crystal, and clock=48M
the seconds seem a few miliseconds off... |

A long shot, but I have run into things like that before where a function (or other "stuff") got compiled in, but was not called and changed the behavior because it moved things around in memory just by being there. I have seen that before.

GPSMikey. It felt that way before, i've kept my old copy of CCS 4.114, compiled an old project,
then compile the same project in CCS 4.130, uploaded to chip..
then compile the code abolve in ccs 4.130 and things seem to work!??
I cant feel confident in CCS 4.130! as Fuses appears to be doing different things and/or there are more options of/else difference!
frustrated a bit though..
thanks everyone, dont normally ask for help i try to read up as much as possible first, but this one bugged me hells over!
---- thank you again folks ---- |

I can't follow the problem report. Uncalled functions are removed during compilation, review the listing file.
Thus there are probably other reasons for reboot. Reboot with 16-Bit PICs should be always suspected
to be caused by a trap interrupt. Methods to catch it have been previously discussed in the forum. |
