/* Pd_Input
* ------------------
*
* This program reads all of the Analog and 12 Digital Inputs
* and sends the data to the computer as fast as possible.
* It reads one analog pin and two digital pins per cycle
* so that the time between reads on all pins remains
* constant.
*
* It was designed to work with the Pd patch of the same
* name in: Help -> Browser -> examples -> hardware
