NFC EEPROM sample application

NFC EEPROM Application based on X-NUCLEO-NFC04A1 expansion board

The application will write an URL to the EEPROM of the NFC tag on your board. This will be able to be read by any NFC device capable of reading NFC tags.

The example uses the EEPROM driver provided for the X-NUCLEO-NFC04A1 expansion board based on the ST25DV04K dynamic NFC/RFID tag.

apalmieri 0:f3d7ca3d45de 7 The example needs to supply a driver for the EEPROM. The `ST25DV` EEPROM driver is provided for the `NUCLEO_F401RE` target. You may wish to update the configuration if you're using a different target.

apalmieri 0:f3d7ca3d45de 12
apalmieri 0:f3d7ca3d45de 13 Verification of the sample application can be seen on any smartphone with a NFC reader. After running you will be able to read the tag with a NFC tag reader application running on the smartphone.

apalmieri 0:f3d7ca3d45de 17 As mentioned above, this example is known to work on the `NUCLEO_F401RE` target which uses the [`ST25DV`](./source/target/TARGET_ST25DV) driver.
apalmieri 0:f3d7ca3d45de 18
apalmieri 0:f3d7ca3d45de 19 If your are not using a `NUCLEO_F401RE` you should indicate in the application configuration file ([`mbed_app.json`](./mbed_app.json)) which driver should be selected by the build system as follows:
apalmieri 0:f3d7ca3d45de 20
apalmieri 0:f3d7ca3d45de 21 ```json
apalmieri 0:f3d7ca3d45de 22 "<TARGET_NAME>": {
apalmieri 0:f3d7ca3d45de 23 "target.extra_labels_add": ["ST25DV"]
apalmieri 0:f3d7ca3d45de 24 }
apalmieri 0:f3d7ca3d45de 25 ```
