Rick, i'm going through the whole process my self right now. For the first time. I'm confident I'll be able to get all the info you need so you should be able to step by step copy paste setup.
However, what I am not sure of is exactly what all is enabled as this point in time cape wise. ADC, I2C, UARTs, PWM, etc. But I can experiment some, and show you how to experiment too in the process, As an aside, I have no circuitry or physical capes to test much, but I should be able to provide enough information for you to learn how to do this on your own ( beaglebone side ). Then if you have physical circuitry on hand, you should be golden. Right now, im dding the console image to an sdcard, next step is booting it up, and upgrading to 3.14.x via APT. My notes thus far as very verbose, so should show others who are unfamiliar with the process of experimentation how it is done. At least how I do it.
