running out of RAM?!

[ye]

Hi everybody,

I am using 18f8722 but due to the massive size of the code, I am running out of RAM....


ROM used: 50186 bytes (38%)
Largest free fragment is 65536
RAM used: 2834 (74%) at main() level
3104 (81%) worst case
Stack: 8 worst case (7 in main + 1 for interrupts)


Can anybody give any indications what else could cause a huge RAM usage besides too many variables?

Whether or not by looking at the LIST file, is there any way to find out which part of the code is eatting significant amount of RAM?

Code doesn't really use up RAM. The compiler does use temporary variables but they are not going to account for a "huge" amount. Strings, arrays, static and global variables are your most likely canidates.

Try to avoid using large data types such as floats. I find most floats could be scaled integers instead. People assume they need floats if they are using trig etc. but with a little though it is not so.

Have you looked at the memory map to see what is using all the memory?
