Every 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.
“RuntimeError: You must start() the PWM channel first”
Any reason why? What’s the max number of same-frequency PWM channels I can have ongoing at any one time?
