[beagleboard] Logic level for PWM, kernel 4.1?

Hi, Is there any way to configure logic level for PWM on BeagleBone Black/Green? I want that in duty cycle, the level of pinout is 0V, instead of 3.3V. I'm using Debian 8 with kernel 4.1. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are

Re: [beagleboard] Logic level for PWM, kernel 4.1?

What I want is, after "reset", the servo motor is supposed to be off, the pin is 3.3V, and when PWM starts, the servo is supposed to be started, the pin is 0V. On Tue, Sep 20, 2016 at 8:40 PM, evilwulfie wrote: you are not making sense. > > pwm pin low - 0v high = 3.3 v > > > -- Quân *

Re: [beagleboard] Logic level for PWM, kernel 4.1?

Hi Robert, So there is no way to config the pin? I want the pin to be 0V when PWM is working, because I want to reduce the power drain from my BeagleBone board to feed the PWM pin. It is similar to why we have GPIO at 0V to turn on the LED. On Tue, Sep 20, 2016 at 9:20 PM, Robert Nelson wrote:

If you don't care about the initial state and when Linux is booting, why don't you just invert the duty cycle in software? That would effectively invert the pin polarity. --- Graham == On Tuesday, September 20, 2016 at 10:07:21 AM UTC-5, Gerald wrote: > > Do a PDF search for the pin number. >

It'll load the w1( one wire ) driver module if not already loaded, then it'll get the temperature from the device every 5 seconds. It'll also load the BB-W1-P9.12 device tree file. I'd assume you'd need to edit this file, or change the overlay file to be loaded if you need to use a different pin.
