* Move pn532 -> pn532_spi Add pn532_i2c * Update i2c address * Always wait for ready byte before reading * Generalise the pn532 a bit more so less code in i2c and spi implementations * clang * Add pn532_i2c to test1 * Try to get setup working * Fixes * More updates * Command consts * A few upgrades * Change text back to include 'new' * Fix data reading
