求一个RFID的arduino读写程序
求一个RFID的arduino读写程序，求高人指点。谢谢~~ wing 发表于 2013-5-14 09:40 static/image/common/back.gif很宽广的课题

我用的arduino MEGA2560。想实现一个对射频卡的读写功能，就差arduino的程序了。
比较难理解 “就差arduino的程序了” 是什么意思。
如果你已经有模块了，只需向提供方要代码就行了，你什么都不缺

arduino通过RC522对IC卡进行读写的程序
//RFID test by Thomas 2012.05.07
int incomingByte = 0; // for incoming serial data
const int ENPin = 2; // the number of the EN pin
int ENState = 1;//default EN state was HIGH
void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
pinMode(ENPin, INPUT);
}
void loop() {
// read the state of the EN value:
ENState = digitalRead(ENPin);
// check if the EN is LOW,the output the data.
if (ENState == LOW&&Serial.available() > 0) {
// read the incoming byte:
incomingByte = Serial.read();
// say what you got:
Serial.print("I received: ");
Serial.println(incomingByte, DEC);
}
}
这是找到的读取rfid的，我想要一个能读能写的，谢谢高手们 本帖最后由 wing 于 2013-5-14 13:16 编辑

522还算大路货，虽然效果一般，但也算对得起他的价格。类似的程序其实很多，下面程序来自某位大神（忘记名字 ...
我想实现的是采用MFRC522射频读写模块在Arduino单片机的控制下实现对Mifare卡的读写访问操作。 /*

我想实现的是采用MFRC522射频读写模块在Arduino单片机的控制下实现对Mifare卡的读写访问操作。
我不算很有经验，不过对RFID比较感兴趣，所以来探讨这个问题。不过冒犯地讲句，您的问题就像挤牙膏......
不知道以下两点是否对您有参考价值：
一. 522的例子网上很多，主要都是基于SPI的，我不确定您6楼的程序是正确的
二.7楼和9楼的程序其实是差不多的，但是您确定您只是想写卡而不是破解 有人用I2C 读卡吗？我今天试了试，总线地址不知道啊！ 水涌沧 发表于 2014-3-22 14:44 static/image/common/back.gif

Stronglink SL018行吗？

只要Rc522的！!!! 水涌沧 发表于 2014-3-23 14:27 static/image/common/back.gif
只要Rc522的！!!!
根据RC522说明书，如果用以下方式连接：
- RC522的 SDA 引脚连接至 GPIO SDA,
- RC522的 I2C 引脚连接至 +3.3V,
- RC522的 EA 引脚连接至 GND,
- RC522的 D7 引脚连接至 GPIO SCL,
** 第一颗RC522的 D6 引脚连接至 GND,
** 第二颗RRC522的 D6 引脚连接至 +3.3V,
- RC522的 D5 引脚连接至 GND
- RC522的 D4 引脚连接至 GND
- RC522的 D3 引脚连接至 GND
- RC522的 D2 引脚连接至 GND
- RC522的 D1 引脚连接至 GND
第一颗RC522的地址是0b0101000，第二颗RC522的地址是0b0101001
如果使用spi，它的Arduino程序库已经很成熟
https://github.com/miguelbalboa/rfid
status = MFRC522_Auth(PICC_AUTHENT1A, blockAddr, sectorNewKeyA, serNum); //认证
请问 认证的时候为啥密码用的sectorNewKeyA，数组里面为啥是 blockAddr/4，而 uchar sectorNewKeyA = {{0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF},
{0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xff,0x07,0x80,0x69, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF},
{0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xff,0x07,0x80,0x69, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF},
}; 相当于 只有 3行数据，要是 blockAddr=63是不是 就没发认证密码了？？？或是认证的为第15行 但是十五行 密码是16个0？？？
