A search of the forums hasn't turned up an answer, so... are there any known issues using digital servos with the Propeller Servo Controller? The behavior I'm seeing is that the position jumps erratically instead of staying at the commanded position. This is more than jitter. My guess is that the servo is seeing erratic or noisy pulses on the input, but I don't have a scope or logic analyzer available at the moment. I'm assuming the PWM is at 50Hz, which both brands of digital servos I tested indicated should be fine. I can't be the first person to have used digital servos with the PSC, so what am I missing?
(pre-answered questions: yes, I have the latest firmware installed. yes, it works fine with analog servos.)
