我買了NFC module from DFRobot，我使用他們的示例程序進行了一些更改，因爲我只想讀取我的標籤的UID。它與隨附的標籤一起使用效果很好，但它不識別我的任何NFC Whiztags（其中包含Topaz 512芯片）。Arduino NFC模塊（DFRobot）不能讀Whiztags
有誰知道我該如何解決這個問題？
這是我的代碼：
#include <SoftwareSerial.h>
/*
# Editor : Adrian
# Date : 2013.04.18
# Ver : 0.1
# Product: NFC Module for Arduino
# SKU : DFR0231
# Description:
# When the a card close to the device , the PC will receive the data
# Connect the NFC Card's TXD, RXD, GND, +3.3V to Nano's D0RX, D1TX, GND, +3.3V
# Or connect the NFC Card's TXD, RXD, GND, +5V to Nano's D0RX, D1TX, GND, +5V
PN532 reads the tag by Arduino mega/Leonardo
command list:
#wake up reader
send: 55 55 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ff 03 fd d4 14 01 17 00
return: 00 00 FF 00 FF 00 00 00 FF 02 FE D5 15 16 00
#get firmware

return: 00 00 FF 00 FF 00 00 00 FF 06 FA D5 03 32 01 06 07 E8 00
#read the tag
send: 00 00 FF 04 FC D4 4A 01 00 E1 00
return: 00 00 FF 00 FF 00 00 00 FF 0C F4 D5 4B 01 01 00 04 08 04 XX XX XX XX 5A 00
XX is tag.
