If the machine Pd is running on has an I2C port and is running linux 
then you can use spidev to access it. Otherwise you need to use a serial 
connection to an off-board microcontroller like the arduino or teensy or 
FRDM-KL25Z to relay messages between the I2C and USB serial connections. 
A lot of motherboards have I2C but it's mainly used for the temperature 
sensors and you don't get access via any header.
