I'm interested in using the Android Things on the Pi 3 Model B, but I need to access a minimum of 4 pins and use them for PWM control.
On the pin-out diagram on Google's Android Things site, there are only two pins labeled PWM 0 (BCM 18) and PWM 1 (BCM 13). Does this mean the other ports aren't PWM-capable? Or is there any library for software PWM for Android Things? And another interesting thing: are pins #27 and #28 inaccessible for the platform? On the pin-out they're just white and have no description.
