 * \brief Accel10 Click example
 * 
 * # Description
 * This example demonstrates the use of Accel 10 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and checks the communication by reading the device ID.
 * After that, performs the Click default configuration.
 * 
 * ## Application Task  
 * Reads the accel values for X, Y, and Z axis and also reads the temperature in Celsius
 * and displays the results on the USB UART each second.
