yego,
The wait_event function takes an event function as the first parameter, not
a sensor number. You need something like (forgive any errors - I don't have
LegOS available at work)
int rotation_event_3(wakeup_t data)
{
if (SENSOR_3 == data)
return 1;
else
return 0;
}
and change the wait_event line to:
wait_event(rotation_event_3,2);

I'd also like to comment that this is dangerous. It's theoretically possible that your sensor (...) (23 years ago, 26-Mar-01, to lugnet.robotics.rcx.legos)
