I think I know what the problem is: Putting a start_process statement
inside a loop like that is going to end up starting so many processes
that the stack fills up almost instantly. I think you probably only
need a single IRCheck process running. Try something like this:
int d; /* note that this is a global variable */
void main() {
int ipid;
sony_init( 1 );
ipid = start_process( IRCheck() );
while( ! stop_button() ) {
printf( "IR data: %d", d );
msleep( 250L );
}
kill_process( ipid );
sony_init( 0 );
}
void IRCheck() {
while( 1 ) {
d = ir_data( 0 );
defer();
}
}
Hope this helps. Good luck!

| HELP!! I keep getting this message whenever I try to multitask with my board: "Not enough stack memory for new process while executing main (process # 1)" The only things loaded are the hb libs, my code and the sony ir routines totally nowhere near (...)
