hello, i am using pic18f4431 for my project and have defined 2 look up tables each of 64 decimal values in the program. when i compile the program, following error occurs, can anyone help ?? i need help urgently.
thanks in anticipation.

 

Error 1300: stack frame too large
The size of the stack frame has exceeded the maximum addressable size. Commonly caused by too many local variables allocated as 'auto' storage class in a single function.

Got any huge local variables in modified.c?

 

Did you put first look up table at line 20?

 

Did you put first look up table at line 20?

yes sir, table is at line 20, if there is one table, there is no error, if there are two, there is error.

no sir, its only a 40 line code with 5 variables and two look up tables each having 64 values. and sorry i cant understand what is meant by 'auto' storage? what i think is that you are talking about static and dynamic memory concepts . kindly explain

 

In this case auto variables are being stored on the stack, and you don't have room for 2 structures. The entire stack is only 256 elements.

Try making them global so they get off the stack.

Actually showing this routine may help someone see a problem.

 

hello,

..i have defined 2 look up tables each of 64 decimal values in the program.

decimal values => type of variable integer , long, float ?

with C18 MPLAB
you can modify your linker file *.lkr
to collapse more than one bank of memory as a big AREA
and then declare your loockup table with this new data name pointer.

example for 4 buffer of 512 bytes
