For those of you testing the machinehum uSD Breakout,  the above scripts will give you something right-away to play with using an led_lab ( described below, see pics above ) and your Pinebook.  Place all ten (10) of the scripts above in a working directory on your gnu+linux Pinebook image, and use   sudo -i  to run the demo_LED.sh script ( or any of the other sub-scripts ).  Each script has been given a title ( important, since they call each other ) and examples following.

The led_lab is six (6) LED(s) on a common cathode ground plane;  the anodes are driven (sourced) by the six (6) SD pins. I used low power ( 2-3 ma ) LED(s) in the following combinations with ballast resistors listed in ohms:

white-330, white-330, yellow-180, yellow-180, white-330, white-330

gpio160 - gpio165

( at this point i am not using the MCP23S17, nor the Padi Stamp )
