STM32模拟SPI总线读写RFID模块RC522
RC522是一款NXP 公司的支持ISO14443A协议的高频（13.56MHz）RFID射频芯片。RFID有ID和IC两种卡应用类型，RC522属于IC卡的应用类型。NFC则属于增强的IC卡类型，支持双向通信和更多类型的协议。
ID卡在制卡时写入一次后，以后只能读取不能写入，常见的Mango卡工作频率为125KHz，所以也叫低频卡，支持ISO 18000-2协议。常见的ID卡右下角有一串打印数字（由ID前十位和ID后八位组成）：
IC卡在发卡时写入信息后，以后通过密码可以读取也可以写入。市面上有比较丰富的RC522可用模块：
卡的内型有标准卡/方形卡和异形卡（水滴形钥匙扣等）。RFID卡通过近距离接收读卡器发送的射频功率用作感应能量来源，以及信号解析密码验证后将卡内的信息发出给读卡器。Mifare卡是市面上最常用，最廉价的RFID卡之一。Mifare卡分为MF0, MF1, MF2, MF3这么几种类型，MF0不带密码控制，使用很少；最常用的是MF1，这种卡带密码控制，分为S50和S70，S50拥有1K存储空间，S70拥有4K存储空间。
关于RC522与卡之间的通讯协议，这里不做仔细介绍，可以参考这几篇介绍：
参考1
参考2
参考3
这里移植参考代码，进行修改优化，实现STM32控制RC522模块读写Mifare卡，执行卡类型识别，卡ID识别，卡存储空间识别，验证密码，写数据，读数据，改变钱包值，备份钱包值。代码基于STM32CUBEIDE开发环境和HAL库。模块采用3.3V供电，可以直接和STM32进行连接。
STM32工程配置
这里采用STM32F103C6T6作为控制芯片，首先建立基本工程并设置时钟系统：
STM32F103C6T6支持USB接口，这里采用USB和UART双通讯输出接口，配置USB接口为虚拟串口：
配置UART接口：
选择5个管脚与RC522连接实现模拟SPI协议访问，STM32的管脚安排如下：
保存并生成初始工程文件：
STM32工程代码
代码微秒级的时序控制，采用的微秒延时函数参考： STM32 HAL us delay（微秒延时）的指令延时实现方式及优化
STM32虚拟串口的设置可以参考： STM32 USB VCOM和HID的区别，配置及Echo功能实现（HAL）
编译时需要采用节省存储的编译方式，参考： STM32 region `FLASH‘ overflowed by xxx bytes 问题解决
功能逻辑设计为：
- UART1为默认数据输出接口
- USB接口收到用户发来的任何数据，才开启USB输出数据
static int8_t CDC_Receive_FS(uint8_t* Buf, uint32_t *Len)
{
/* USER CODE BEGIN 6 */
extern uint8_t USB_Status;
USB_Status = 1;
USBD_CDC_SetRxBuffer(&hUsbDeviceFS, &Buf[0]);
USBD_CDC_ReceivePacket(&hUsbDeviceFS);
return (USBD_OK);
/* USER CODE END 6 */
}
- 循环进行卡类型识别，卡ID识别，卡存储空间识别，验证密码，写数据，读数据，改变钱包值，备份钱包值

/*
复位操作：
开启天线
关闭天线
复位RC522
设置RC522工作方式
通讯操作：
寻卡，通过RC522和M1卡通讯（数据的双向传输，从而确定卡片的卡型。）
防冲突（当有多张卡片进入读写器操作范围时，会从中选择一张卡片进行操作，并返回选中卡片的序列号。）
选定卡片(用RC522计算CRC16（循环冗余校验）)
校验卡片密码（三次相互确认）
在M1卡的指定块地址写入指定数据(M1卡分为16个扇区，每个扇区有4块，实际操作时，将16个扇区分为64个块，按绝对地址编号0-63)
读取M1卡的指定块地址的数据
让卡片进入休眠模式
S50（M1）卡基础知识：
1.每张卡有唯一的序列号共32位
2.卡的容量为8Kbit的EEPROM
3.分为16个扇区，每个扇区分为4块，每块16个字节，以块为存取单元
4.每个扇区都有独立的一组密码和访问控制
扇区0的块0用来固化厂商代码
每个扇区的块3作为控制块，存放：密码A(6字节), 存取控制(4字节), 密码B(6字节)
每个扇区的块0，1，2作为数据块，其作用如下：
1.作为数据存储，可以对其中的数据进行写卡，读卡
2.用作钱包数据值，可以进行写卡，读卡，加值，减值
对数据块的操作类型：
读（Read）:读一个块的数据
写（Write）：在一个块中写数据
加（Increment）：对数据块中的数据进行加值(充款）
减（Decrement）：对数据块中的数值进行减值（扣款）
传输（Transfer）：将数据寄存器中的内容写入数据块中
中止（Halt）：暂停卡片的工作
要设置一个块为数值块，它的格式是非常严格的，必须按照数据块的格式去写，才能调用充值和扣款的功能:
|字节0|字节1|字节2|字节3|字节4|字节5|字节6|字节7|字节8|字节9|字节10|字节11|字节12|字节13|字节14|字节15|
| 钱包值 | 钱包值反值 | 钱包值 |地址 |地址反|地址 |地址反|
Mifare S50在出厂时，每一个控制块的密码A和密码B都为FF FF FF FF FF FF
