/**
******************************************************************************
* How to use this sketch
*
* This sketch uses the I2C interface to communicate with the NFC device.
* It writes an NFC tag type URI (Uniform Resource Identifier).
* Choose the uri by changing the content of uri_write.
*
* When the NFC module is started and ready, the message "Sytstem init done!" is
* displayed on the monitor window. Next, the tag is written with the content
* printed on the monitor window.
*
* You can use your smartphone to read the tag.
* On Android, check if NFC is activated on your smartphone.
* Put your smartphone near the tag to natively read it.
* The preferred Internet Browser is automatically opened with the provided URI.
