Does anyone know how to handle stack?
I point exactly to the stack size.
For many reason that embedded system has limited of resource including stack also .
Unfortunately 8051 allow sp to allocate itsleft only in internal ram which can't be expanded by external data.

I've asked many one and they say that "run most function as much as possible", I think it's very simple and it's in common sense of any one here .

This subject include realtime system also .
Do anyone have suggestion?

Best regards
