 * @brief Accel 28 Click example
 *
 * # Description
 * This example demonstrates the use of Accel 28 Click board by reading and
 * displaying the accelerometer data (X, Y, and Z axis).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver, performs the Click default configuration.
 *
 * ## Application Task
 * Reads and displays on the USB UART the accelerometer data (X, Y, and Z axis)
 * when it is available.
