 * @file main.c
 * @brief OLEDB Click example
 *
 # Description
 * This example demonstrates the use (control) of the OLED B display.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Configures the microcontroller for communication and initializes the Click
 * board to default state.
 *
 * ## Application Task
 * This section contains the main program that is executed showing a practical
 * example on how to use the implemented functions.
