 * @brief Accel 27 Click example
 *
 * # Description
 * This example demonstrates the use of Accel 27 click board by reading and displaying 
 * the accelerometer data (X, Y, and Z axis) averaged from 100 samples.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Reads and displays on the USB UART the accelerometer data (X, Y, and Z axis) averaged from 100 samples.
 *
 * @note
 * This click board should be used for high g applications of up to +-400g. It is not recommended
 * for low g applications because of its high scale factor which is about 200 mg per LSB.
