1) See how much RAM your chip has.
2) See how much RAM all your variables and data structures take.
3) Allow a little for compiler scratchpad if you are using any complex lines of code.
If it doesn't fit you need to:
1) Use a bigger chip.
2) Use fewer variables, reuse variables, use shorts instead of ints, use smaller buffers etc.
3) Use simpled C lines so the compiled doesn't need so much scratchpad. _________________ The search for better is endless. Instead simply find very good and get the job done. |

And, for most chips in the 16-series, with the PCM compiler you
can enable use of all RAM with the #device *=16 statement, as
shown below:
Code: | #include <16F877.H>
#device *=16 // <== Add this line, at this exact location.
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
//==================================
void main()
{
while(1);

Hello,
I was looking for why I was out of memory with only half of used variable.
And I found this post.
I always asked me for the interest of this option, now I know
Thanks a lot for your help
