// Example Code for a I2c implementation on Microchip PIC18f46J50
// You are free to use as you wish, but it is supplied 'as is'
// Tiertex Design Studios shall not be liable in any circumstances for any damges arising
// when using this code.
// The code below uses simple software polling techniques for I2C communication. For more efficient
// code use interrupt polling instead.
// This code is not intended to compile as is but is a collection of routines taken from the USB
// CDCSerial Demo for the I2C add-card based on the Tiertex PIC18F46J50 demo board.
