Hi Everyone,
I am using PIC16F1947 MCU.
CCS PCWHD Version 4.118 compiler.
I am facing lot of problems with this version.
When I add I2C routine in code, cpu get reset.
It may be because of stack overflow.
Please guide me if someone has information?
Thanks in advance......... |

| you'll need to post a short compilable program that replicates the issue and post it here using the code tags (not the quote ones). That way you can get some better help. |

Look at the sixth word in Jeremiah's suggestion. Do you think this qualifies....
Seriously, this is part of debugging. If you have a problem like you are describing, then use an absolute minimum program, and try talking to just one I2C device. If the problem doesn't then show, add another.
As it stands, _you_ need to cut the code down, and in doing so, you may well find the problem. If not, you then have something small enough that we can help. |

| 16f1947 problem |

Code works fine when it is in small pieces.
e.g. when i add only RTC , it works fine.
when i add RTC+EEPROM,it works fine.
but when i add more than this CPU reset.
then it doesn't matter wheither code is of ADC or keypad or simple display function.
i think it's problem to jump next code bank.
adding list file for same:
ROM used: 2174 words (13%)
Largest free fragment is 2048
RAM used: 49 (5%) at main() level
67 (7%) worst case
Stack: 5 worst case (2 in main + 3 for interrupts)

What value are the I2C pullup resistors ?
Have you tried another version of the compiler ? |

Pull up resistor is 10K.
I haven't tried for another version.
i will try it.
Thanks for your valuable advice.

| 10K seems high to me, I use 3k3 or 4k7 when running 5 volt PICs. |

OK, i will try 4K7.
but pull will not display data from RTC/EEPROM/ADC.
why this will reset CPU?
Confused.

Problem was when my code jump from page 1 to page 5 it wont works.
It may be because of pointer.
CCS need to solve this problem.
Now I am facing new problems.
1. I can not use two serial ports of PIC16F1947.
I can use only UART1 of this ic.
There no interrupt given by CCS for Serial two.
2. When my code exceed more than 60%, some functions get corrupted.
Suppose function 1 is first having more than 1000bytes code.&
function 2 is next to it having 1000 byte code.
Then function 2 get corrupted. Same function 2 when i cut & paste above function 1 then my function 1 get corrupted.
When I saw call tree in CCS, the function moved to Page 5 not work properly. So please tell me solution for this.
Should I optimize my code to below 50%. Or this bug is fixed in newer version. My compiler Version is 4.114.
Waiting for your reply...........

Great!
Two people tell you to post a short listing and your response is to post an even longer listing. 
With short we mean max. 1 screen page.
After scrolling down down 10 pages I thought it was getting really long, but it continued on, and on, till 48 pages... (just curious, I counted them all).
Sorry, but now I've lost interest in reading the rest of your post.
If you don't want to put effort in making your program smaller, then you haven't learned how to hunt for bugs and I'm not going to waste my time helping you. |

1) the spec sheet says it has 2 hardware UARTS....
2)one solution is to show us SMALL,tiny, ittybitty program that has your problem...as others have pointed out |

The chip does have two UARTS. They are also in the device database
but the second one is not in the header file. Those entries need to
be added to the header file. Send a message to CCS asking for an
updated file.

Dear Sir,
This code is not for debugging purpose.
I am working from last 3 year on CCS cross Compiler.
I have that much experience.
I am just sharing problem so that other guys will take some solution & do not repeat same.
I have solved code error & now only waiting for 2 serial port & above 60% code problem.
Whatever code i uploaded is begining stage of my software.
Now i have optimize & reduces unnecessary routine to avoid this error.
but i can only avoid this, not to solve this.
thats why am doing this.
Thanks again for reading my overviews.
