Testing control of 2 servos connected to a Raspberry Pi. I am using the Python bindings of the pigpio library for generating concurrent PWM signals for each servo. The PWM pulses are timed using the DMA controller on the Pi, so the resulting signal is much more accurate than software PWM (stuff you get with RPi.GPIO), and more than sufficient for smooth servo control.
