/*
  This module is designed to inteface a 16 bit microchip processor with the 12 bit DAC.
  
 */

/*
  This module requires that the I2C bus be initialized externally before calling any of the read or write functions.
  The exact numbers will vary based on the frequency of your OSC and the Frequency that you want the bus to run at.
  Initialization should look something like this.
  Initialization will vary slightly between 24,30, and 33 series chips.
  See i2c.h for more information
