  MPLAB Harmony Application Header File

  Company:
    Microchip Technology Inc.

  File Name:
    app_i2c.h

  Summary:
    This header file provides prototypes and definitions for the application.

  Description:
    This header file provides function prototypes and data type definitions for
    the application.  Some of these are required by the system (such as the
    "APP_I2C_Initialize" and "APP_I2C_Tasks" prototypes) and some of them are only used
    internally by the application (such as the "APP_I2C_STATES" definition).  Both
    are defined here for convenience.
