Awesome, glad it was of some use! Do check out my Switch thread on this board; it covers the sensor documentation in a little more detail and I had uploaded a (now rather pointless) schematic for the PCB while exploring input types.
The more useful part to you will be the various ways of talking to the board. Since you have the Intel itx, you should be right to use the same method I did with the polarity checking. However if you choose to move to a different board later, there are additional topologies briefly covered for handling different cases.
