    Oh and one other thing I've noticed,which may be causingn the PIC to bomb is when the when the wiper is at the top and thus connected to the 5.21v supply the pulses stop and the voltage out drops, and on some occasions this has caused the driver to sort of lock as moving the pot after the effect has no effect as the PMW generation has stopped. Is there a way of setting the voltage ref or ADC value so that a PMW signal is always produced ?

    Edit:
    maybe this video might help explain (2.2 MB Divx format) http://www.micro-heli.co.uk/scope4.avi
