I2C support #1

Closed tprochazka closed 11 years ago

Do you have in plan also I2C support?

xiongyihui commented 11 years ago

There is a library to SPI and I2C: https://github.com/xiongyihui/PN532.git. But peer to peer communication doesn't be supported by I2C. The I2C(Wire) library of Arduino only supports to send max 32 bytes packet at once. But peer to peer communication needs to send a packet more than 32 bytes.
