While the libraries do not officially support the Due yet, some customers have been able to get them working with some minor changes to the library.

Bien que la bibliothèque ne soit pas officiellement supportée sur Arduino Due, certain client on réussit à faire fonctionner la carte à l'aide de quelques changements mineurs dans la ibliothèque.

We recommend using the I2C libraries with both the shield and the breakout boards since the I2C library represents the latest code from Adafruit, and the shield version should work without too much effort.

Nous recommandons d'utiliser la bibliothèque I2C avec le shield PN532 et la carte breakout PN532, la bibliothèque I2C est la plus récente produite par Adafruit et la version shield devrait fonctionner sans trop d'effort.

There is one caveat combining the breakout, I2C and the Due, though: '''The Due includes pullup resistors for I2C0 (SCL0 and SDA1), but there are no pullups resistors on SCL1 and SDA1. SCL1/SDA1''' are the pins used as replacements for the Uno I2C pins (the pins used on standard shields), so you will need to add two 1.5K pullups on SCL1 and SDA1 to use the breakout board with I2C1 and the Due. Simply solder two 1.5K resistors, one from SCL1 to 3V3 and another from SDA1 to 3.3V, and then connect the board the same way you would with an Uno.

Il y a un avertissement concernant le breakout, I2C et Due. '''Le Due inclus des résistance pullup pour I2C0 (SCL0 et SDA1), mais n'a pas de résistances pullups sur SCL1 et SDA1. SCL1/SDA1''' sont les broches utilisées comme remplacement pour les broches I2C d'un arduino Uno (les broches utilisées sur un shield standard), il faut donc ajouter deux résistances pullup de 1.5K sur SCL1 et SDA1 to use the breakout board with I2C1 and the Due. Simply solder two 1.5K resistors, one from SCL1 to 3V3 and another from SDA1 to 3.3V, and then connect the board the same way you would with an Uno.

'''This issue only applies to the PN532 Breakout board since the PN532 shield includes I2C pullup resistors right on board'''.
