ESC32 V3 can't be used on PWM

Postby oscar0613 » Sat Jun 17, 2017 5:47 am

Hi everyone:

I bought a ESC32 V3, and I've installed it well.
Finally, I can calibrate it on computer, but can't use it on PWM receiver.
My equipment is Futaba R7008SB, and it can work well on servo motor, but when I change it on the ESC32 V3. it is died, can't work.
I've checked the filed in this form, and I know I need to correct the parameter of PWM_MIN_PERIOD = 2200 us
PWM_MAX_PERIOD = 25000 us
Unfortunately, it still can't work.
Can anyone tell me what's going on? Is that the problem of the line connection? or about setting? and how to correct it?

Please see the following video of what I've done.

Looking forward to hearing from you.
Thank you very much.

Did you try to disconnect the USB Connection ? It should be only one interface ( pwm or USB) possible.
