[beagleboard] Re: PWM on more than 4 pins?
Which pins are you using? P9_14 P9_22 P8_12 and P8_14 work just fine for me On Sunday, March 2, 2014 2:24:31 PM UTC-5, ghostma...@gmail.com wrote: very time I try to use certain PWM pins on the BeagleBone Black I get this error for most of the pins (from the ones shown in yellow here: http://beagleboard.org/static/images/cape-headers-pwm.png) I am using Ubuntu on my BeagleBone Black.

What's the max number of same-frequency PWM channels I can have ongoing at any one time? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Woops sorry, my mistake. I have PWM on P9_14 and P9_22 On Mon, Mar 3, 2014 at 10:14 AM, Andrew Dai the...@andrewdai.co wrote: Which pins are you using?

Re: [beagleboard] Re: PWM on more than 4 pins?
Firstly, the working pins tend to change randomly... Cos P8_13 works for me. Secondly yeah, I do get a set of 4 working PWMs but I need more than that, I need 5 pwm. I am trying to work with the Adafruit library but that gives me this error when I try it on some of them. Even the pyBBIO library doesn't support pwm outputs with the 3.8 kernel. At this point I think that a stable version of the 3.2 Angstrom distribution will fit my needs as it is much easier to set the pin muxes. Does anyone know where to get them?
