All modifications were comments to state that no pull-ups and pull-do…

…wns were to be used in hardware or in the INPUT port configuration for the uC.

No functionality changes.

+**** IMPORTANT NOTES BEFORE BEGINNING
+**** 1) The TS4231 is a 3.3V device and must only be used with a 3.3V Arduino board.  Failure to do so will damage the TS4231.
+**** 2) DO NOT add pull-up or pull-down resistors to the D and E signals.
+**** 3) DO NOT configure the Arduino INPUT ports that connect to the D and E signals with a pull-up or pull-down function.  They must be floating.
 
 1) First, install the TS4231 Arduino library by following the instructions here:
