stm32duino/ST25DV: Arduino library to support ST25DV components

Arduino library to support the NFC ST25DV components:

This NFC sensor uses I2C to communicate. It creates the instance st25dv.

It is then required to call begin API:

Or you can make your own instance of the component

    TwoWire MyWire(SDA_PIN, SCL_PIN);
    ST25DV st25dv(gpo_pin, lpd_pin, &MyWire);

It is then possible to read/write NFC URI:

    int writeURI(String protocol, String uri, String info);
    int readURI(String *s);

There are 2 examples with the ST25DV library:

When the NFC module is started and ready, the message "System init done!" is displayed on the monitor window. Next, the tag is written, we wait few seconds, we read the same tag and print it on the monitor window.

You can test this application by connecting it with your smartphone. On Android, download a NFC Tools. Then start the app, check if NFC is activated on your smartphone. Put your smartphone near the tag, you can read it. You can write a tag with this app.

When the NFC module is started and ready, the message "System init done!" is displayed on the monitor window. Next, the tag is written with a URI.

You can test this application by tapping the tag with your smartphone. On Android, check if NFC is activated on your smartphone. Put your smartphone near the tag to read it. The preferred Internet Browser is automatically opened with the provided URI.
