I2C:

Still not working but here are some notes.

• The usb-i2c adapter has the pull up resistors for the sda/scl lines built into the pcb.
• start, stop, acknowledge bytes are handled by the i2c master and do not need to be done manually
• Finally figured out how to use the i2c test application.  The chip seems to be working but it is changing the values for both registers instead of only one.  At least I know the address I was using is right.  I think the c program is not writing properly because whenever it writes, a green led should light up on the adapter.
