[CCC DEV] Servo implementation question

[Matt Jadud]

Hi all,

We can implement servo control one of two ways:

1. Use hardware PWM.

2. Fire a timer every 20ms, and drive an arbitrary digital pin high
for somewhere between 600us and 2400us. This would allow us to
(possibly) control more servos than we have PWM pins. However, while
driving servos, we are out of the VM.

Opinions either way?

Cheers,
M
