此程序为13.56MHz的RFID底层读写卡程序

说明：  RFID DEMO UHF FOR READERS OVER SERIAL PORT

从网上下载的STM32 IAP源码和测试代码，已经移值到我自己的板子上，很容易，和大家共享。(Downloaded from the Internet STM32 IAP source and test code, the value has been moved to my own board, it is easy, and share.)

RFID超高频扫描模块通过串口与单片机连接，使用用户手册中提供控制指令进行编程，对RFID扫描模块进行简单控制，实现扫描模块的自动扫描，可控制扫描周期，只需修改延迟时间，同时通过LCD12864进行显示···· （提供扫描模块用户手册）

基于ZigBee协议的温湿度采集系统，节点将采集到得温度、湿度和光强无线传输，协调器接受并显示多组节点数据，文中带中文注释。-ZigBee protocol based on temperature and humidity acquisition system, the node will be collected were temperature, humidity and light intensity radio transmission, coordinator node to receive and display multiple sets of data, text with Chinese comments.

Viterbi编码解码算法，C源码，有仿真。-Viterbi decoding algorithm code, C source code, has simulation.

说明：  某宝商家的工具，原本需要注册，自己破解了免注册，PN532红板+ch340的TTL亲测可完美写uid、cuid卡，可进行key破解，可在配置文件写入已知的key，内附使用说明(NFC pn532 uid cuid)

LDPC中的q进制编码算法，已经通过，由m语言也有c语言(Q in M-ary LDPC coding algorithm, has been passed by the m language also has c language)
