Hi,
I�m using a CCS C Compiler to program a PIC16F877. I use that thorough MPLAB Plug-in from CCS in order to use my PICStart Plus Programmer. But when the code starts grow this error appears.
MPLAB Output Screen:
++++++++++++++
main
Seg 00800-00FFF, 0555 left, need 0829
0001
Seg 01000-017FF, 0800 left, need 0829

| You function is too big. Try breaking it up into smaller pieces. If you only call a function once then try adding #separate before the function or else the compiler will place the code "inline" and your function will be larger than expected. |

Hi,
Will writing #SEPERATE before a large function solve the problem, I have faced this problem quite frequently, what I usually do is to break the large function/procedure into smaller ones.
I did'nt know #SEPERATE could solve this problem...
thanks

It won't "break up" a large function. For example:
| Code: |
void funcA(void
{
....
}
void funcB(void
{
....
}
void funcC(void
{
....
}
void funcD(void)
{
funcA();
funcB();
funcC();
} |
In the above example, if we only call the functions once, funcD will be one big function. That is, the compiler will place the A,B,C functions "inline" as an optimization technique. By adding #separate before functions A,B, and C, the compiler will treat these as individual functions which would be smaller and have a better chance of fitting into a code page. |
