We chould generate the docs with a --libsimpleservo build, but that would cut out the docs from ports/glutin. It would be nice if there were a way to merge the two builds somehow.

Not very good implementation of the selecting and releasing the channels for the ledcSetup() function:

Tip: implement by std:bitset to remember used channels.

I have had some trouble finding some of the software to install. apt-get and pip seem to not recognize them. Could you post an Install guide?

On the Arduino, the writeMicroseconds method of the Servo class is useful for calibrating servos that don't align directly with the 1-2ms range. An equivalent function or field in the servo class would be more convenient than setting the pulse width range to a wide value and calculating the actual limits.
