Tux,

Your confusion is based on what a PWM is. For nearly everyone except the radio control crowd, a 50% PWM wave is a square wave. Likewise, a 0% PWM signal is a steady DC signal at the lower rail (usually 0 volts) and 100% is a steady DC signal at the upper rail (usually 5 or 12 volts). I would call this definition "classical".

In the RC world, a 1 ms pulse every 10 milliseconds is neutral, whereas a 0.5 ms pulse is full reverse and 1.5 ms is full forward.

The default for our PWM signals is the RC type. The code example you cited will allow you to create a "classical" PWM signal.

This classical PWM output will not help you get more rotation out of a servo.

Now, let's address your problem:

My suggestion is to tandem two servos together. Just align the axis of rotation and attach the dial of the first servo to the back of the second servo (plastic epoxy would work just fine) and connect both servos to the same RC PWM output via a Y cable. This would give you approximately +/- 180 degrees of rotation versus the +/- 90 you get from one servo and would have been legal by this years rules.

Hope this helps...
