| Strange and Big Problem! |

Hi,
I have a big problem, I have a firmware and when I add a new function the USE RS232 (soft) not work. I compare the two USE RS232 (ok and bad) and I see some differences but I not understand why?????
I need that you help me with this problem, I have two days working in solve this and I cannot, my customer want kill me!!! I think that the problem is when send bytes...
Any IDEA???
Thanks!!!
I use the last version with a 24HJ256GP206A

I don't use that PIC but...
1) both #use rs232(...) appear to have the same options,so they should be the same. You don't point out the differences which would up my tired eyes.
2)they compile at different memory spaces.
that leads me to believe you've modified other code that we don't know about.
You should post a small compilable program that shows us the problem.
Without seeing the real program I can't understand where the problem is.
We need some more information.

Key thing is 'what happens'. Are the bytes being sent, but corrupted?. Or is the processor crashing?.
If so, then you are almost certainly getting a trap interrupt.
Only 'user' interrupts are disabled.
Normally a trap would cause a reset, but if you have enabled you own trap functions 'anything is possible'. How big is your stack?. Adding the extra function may have simply taken you over the stack size allocated. |

I can see that the problem is when I define global large array > 2Kb. I don't know why happen this, I have too much ram. I send a email to CCS.
