RC PWM pulse range
  • I am working on an RC controll system to control the pointing of the camera. I'm using an arduino to generate PWM pulses which are then sent through an RC transmitter module. From testing it appears the transmitter limits the pulses to between 900 and 2100 microseconds. When I direct connect the arduino to a servo I get a larger usable range about 750 to 2400 microseconds. I assume the controller expects the pulse width to fall into a specific range. I need that range so the arduino is consistent with the controller. Does anyone know what that range is? The gimbal is with my son in a different city so I can't check it myself.
