no error but code crashed after one float variable defined
PostPosted: Tue Oct 18, 2005 8:40 am     Reply with quote
Hiiii everybody !...


Please help !!!

I am in trouble badly.

I have a code working perfectly on PIC18F452.

But, If I add (define) a float variable to the code,

My code is crashed.

My CCS ver is 3.203 (not bad I think)

No error messages.

The Compile is OK

Memory use is about %25 for ROM, %30 for RAM.


Any urgent help will be appreciated...

Could be a buffer overrun problem and adding the float exposes it.

Are you using a bootloader? If so which one?

Besides all the remarks of the people above I was triggered by the following:

Do you have a special reason for using this version? The early v3.20x versions have new optimized code for the PIC18 processors but were very unreliable. The first version I dared to try was v3.216. If you don't have access to the newer versions I suggest you revert to the stable v3.191.
