Recurison on a PIC16F877A
PostPosted: Sun Nov 14, 2010 1:31 am     Reply with quote
I tried to re-call a function. It told me recursion is not permitted any ideas?

With prototype headers
Code:

void start();
void end();
void main();

void start()

{

end();
//It will tell me that recursion is not permitted?
}

void end()
{

}

void main{

}

Don't use recursion.....
Problem is that the PIC, does not have a data 'stack'. So subroutines can't have temporary variables that go to different locations each time the function is called, without a lot of extra coding. So a routine cannot be called inside another copy of itself - 'no recursion'.
What you post, won't give the error you are talking about. However if you change it so that end contains a call to 'start', it will.

Best Wishes
