PIC24EP512 Stack Size Warning

Device: PIC24EP512GP806
Compiler: 5.026

Hi again guys,

Another question beyone my scope of understanding!

I've been using <#build stack = 1024> for the longest time but just now I've seen this message from the compiler:

>>> WARNING 202: {filename}: Stack size needs to be increased. Stack may be too small, try 1558 bytes.

So, question is should I increase it to that specific value or should I just double it and go straight to 2048?


If I increase it to 2048 warning goes away although code seems to be working as expected with 1024 although I get the warning.

Are there any inconveniences or advantages of putting directly 2048 instead of 1558?

Thanks!

Ben

None. Just more RAM used.
It does suggest you have a huge number of functions using a lot of
variables.

Ah ok thanks.

And yes indeed, it's a monster of a program.

Doubling the size from 1024 to 2048 makes my RAM usage go from 41% to 42% so really that's nothing.

Thanks again!

Ben
