Adafruit offers a NFC breakout board which is also packaged as a full kit including a mbed & other parts to get you started.

Getting Started¶

Wiring it up¶

First of all pinheads need to be soldered on the board's main connector as well as on the two jumpers' location.

The board's NFC controller (PN532) can either be configured for serial, I2C or SPI communication. The stack is currently configured to use SPI so the jumpers need to be configured accordingly: SEL0 off and SEL1 on.

Now the relevant pins must be connected to the mbed.

Test¶

This program demonstrates how to transfer data between a phone application and your mbed. In this version it just dumps a text entered on the phone on the mbed USB serial interface, and transfers another text back for display on the phone.

The default pin mapping for this program is the following but you can change it in the MuNFC constructor's parameters.

Load the program, reset the mbed and approach you Android NFC phone!

You should be able to download the app from the Google Play Store. Then, tap the device again and you will get the interface.

Software¶

The µNFC stack is available as a library; it is fully documented with Doxygen.
