Examplesdescription
System Initialization - Initializes peripherals, UART interrupt and pins.
Application Initialization - Initializes click driver.
Application Task - The click enables barcode scanning in 2 seconds intervals and then disables
scanning also in 2 seconds interval. When the barcode is scanned, UART interrupt will be
enabled and the barcode will be stored in the temp buffer.
