Hi,
Im very new to propeller building/programming. I have a cont. rotation servo from parallax and the propeller PE education kit. Now I wanted to connect the servo to chip. I can't find an example how to do this. I hope someone can tell me where I can find a good example.
Regards,
Patrick

The preferred circuit of choice is to place a 4.7K resistor on each signal input
to the servo. If long leads are used, place a 1000uF cap at the servo power
connector. Servo's seem to be happy with a 5V supply receiving a 3.3V signal.
You need this resistor to limit the current flowing from the servo to the prop in case the servo "send" 5V to the propeller-chip
