The following will be in the next release of SNAP and Portal Pro, but here is a sneak peek.
RF Engine pin GPIO 0 supports PWM in hardware. I will be attaching three files to this post:
PWM.py - provides basic access to the PWM functionality
ledCycling.py - a demo that uses PWM.py to vary the brightness of the LED on a SN163 Bridge Demonstration Board or a SN111 End Device Demonstration Board (the SN171 Proto Board does have LEDs, but not on the correct pin)
servoControl.py - a demo that uses PWM.py to position a standard servo motor (like R/C cars and planes use). This demo would be run on a SN171 Proto Board.
Look in the scripts themselves for more details.
