Hello,

I am worikng on a robot used for room mapping.
Can you give me some advice about the algorithm, because there is a 
problem. I try to implement  a recursive function that searches all 
free locations in the room. The problem is that I will sure receive a 
stack overflow message.

So, the question is: Do you know how to increase the stack limit?
Or do you reccomend another algorithm?

I use ATMEGA162 with no external memory and CodeVisionAVR, under 
Windows 2k
