MultiWii 2.3 not outputting PWM signal

Post by Seigfried »

Hi, everyone
I have a MultiWii Pro running v2.3, and my ESCs are beeping the no signal beep. They work fine, I tested with just a receiver. The ESCs are Afro 20A. I tried calibrating them to the throttle range of my radio first, but that didn't work either. The board worked fine with v2.2. Can anyone tell me a reason ESCs woulden't get a signal?

Either your wiring of the ESCs is not correct
or you are using a faulty arduino beta version.

I was facing the same issue when I used arduino beta 1.5.1 or 1.5.2 resulting in a missing PWM output.
Every issue was gone when I switched over to beta 1.5.3 or higher or when I stayed at 1.0.5...
