 * \brief Grideye Click example
 * 
 * # Description
 * 64 individual thermal sensors build an image on a display. The detecting distance is 5m.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes I2C driver, applies default settings, and makes an initial log.
 * 
 * ## Application Task  
 * This example demonstrates the use of Grid-EYE Click board by reading full grid and displaying values via USART terminal
