From the eagle file it looks like the protocol selection PINs of PN532 are hardwired to SPI (S0-LOW; S1-HIGH) in Seeedstudio NFC shield. Is there an easy way/hack to change it to I2C (S0-HIGH; S1-LOW)?
(I want to use I2C instead of SPI because I need free digital PINs available for my project in Arduino UNO and I2C will only require analogue PINS)
