 * @brief NTAG5Link Click example
 *
 * # Description
 * This example demonstrates the use of NTAG 5 Link click board by programming the
 * specified NDEF URI record to the memory, and showing the memory read/write feature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger and performs the click default configuration which 
 * enables the device and formats its user memory. After that it programs the specified 
 * NDEF URI record to the memory.
 *
 * ## Application Task
 * Writes a desired number of data bytes to the memory and verifies that it is written 
 * correctly by reading from the same memory location and displaying the memory content 
 * on the USB UART approximately every 5 seconds.
