 * @brief IRGrid3 Click example
 *
 * # Description
 * The demo application displays a reading of ambient temperature and 
 * a 32x24 pixel object temperature matrix.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configures the Click and log objects and sets the Click default configuration.
 * 
 * ## Application Task  
 * Reads the temperature of all pixels every 500ms 
 * and displays it on USB UART in a form of a 32x24 matrix.
