I just got the Turnigy Multistar 20 Amp Multi-rotor Brushless ESC 2-4S.
I have a motor and a battery hooked up to the ESC. On the three pin connector, I attached the brown ground wire to a ground pin, and yellow signal wire to a PWM-capable IO pin. I'm trying to figure out how to send motor signals to the ESC, with no luck. I know that I need to send PWM output through the yellow signal wire, but I don't know the frequency or high time of the PWM signal. Also, I've read that certain ESC's have an arming procedure, and I'm not sure how that works.
How do I control my ESC from a generic output pin hooked up to a microcontroller?
