Using Arduino with Ada

AVR-Ada and PN532, part 2: Mifare Classic, Yubikey NEO, I2C support

I continued tweaking my PN532 code and during the past few months I have added support for I2C interface, Mifare Classic tags (read-only), and Yubikey NEO keys (NFC Forum Type 4 interface).

PN532 and Arduino

I2C support means that you can use Adafruit PN532 Arduino Shield and normal Arduino UNO to run my ...

Read, write, and emulate NFC tags using Adafruit PN532 breakout board, Olimexino-328, and AVR-Ada

Recently, I have been playing with PN532 breakout board from Adafruit to read NFC tags and to communicate with NFC-enabled devices, like smart phones.

Adafruit's PN532 breakout board uses 3.3V voltage level and it is little tricky to use it with normal Arduino. So I ended up using ...
