Add servo control #44

Closed GoogleCodeExporter closed 9 years ago

For the servomotors, a frequency of 300Hz could be sufficiently low (the
period should be between 3 and 20milliseconds). And then, the time at the
high state will determine the output angle of the servomotor (between 0.5
and 2.5ms approximately, depending on the type of servomotor).

So either you can set a frequency between 400Hz (=2.5ms at the high state)
and 2KHz (=0.5ms at the high state) to drive the servomotor. Or you can set
a fixed frequency of 300Hz for example and change the duty cycle to change
the output angle of the servomotor.
