Compiler problem

Mancio · Guest

Hi,
I've got some trouble with the compiler.
When I compile the program, everything seems to be correct but the program occupancy still ramain 1%, even if there is a lot of code.
Examining the .stm file, it seems that the assembler code is not generated.
What can I do?
Thank you

Do you have more than one source file?
Do you have any #if's?

Yes I've got some files.
I've just find an error in the definition of .h file.
I've wrote #device *=16 instead of *=8 and now something work with the RAM occupancy.
But with ROM nothing to do. Still at 1%.
I'm working with PIC18F4620 and it's my first time with pic18 family.
Previously I've worked without any problem with PIC16F876.
I compile but ROM wont grow up!!

#device *=16 and *=8 aren't necessary for the PIC18's. My guess is that you are not including the other source files in you main C file.

It would be easy to help if you post a short sample of your code. It doesn´t
matter the code you can add, the compiler would not generate any code related
to the "code increase" if inside main() the functions are not invoked.
Anyway the 18F4620 is a 64K device and to see 1% step growing you would
add 8x in the code size compared with the 16F876.

Thank you everybody.
With yours helpful directives now I've seen that everything works!!
Once again thank you.
For the ROM problem... I havent put any instruction in the main().
Just adding some functions and the ROM occupancy grow up
