RS232

一个串口写卡程序，能够读卡片显示内容，很好用的。(A serial write card program that can read the card display, very good use.)

该源码公示了怎样使用STM32F407的串口进行收发数据，在keil5编译环境中进行编译。需要将STM32F407的串口1与USB串口相连，即可以实现电脑桌面串口调试助手的调试。(The source of the public how to use STM32F407 serial port to send and receive data, compiled in keil5 compilation environment. We need STM32F407 serial port 1 is connected to the USB port, which can achieve desktop debugging serial debugging assistant.)

支持电力规约645，376.1等相关规约的485代码，支持常用电表控制信令代码，(Support the power of the Statute 645,376.1 Statute 485 and other related code, support for common control signaling code meter,)

清除串口冗余。当下位机偶然有乱码出现时，在新的通讯开始先清除缓冲区冗余信号，然后开始通讯，可以保证通讯更稳健(Clear serial redundancy. Current-bit machines have occasionally garbled when, in the new communications start to clear the buffer zone redundant signal, and then began to communications, to ensure more robust communication)

CSerialPort.h CSerialPort.c VC++串口通讯类，用于初学串口通讯，及串口通讯原理有一定帮助。(CSerialPort.h CSerialPort.c)

封装较完整的串口类库，适合硬件开发人员使用，欢迎下载！(Packaging more complete serial library suitable for the development of the use of hardware, download welcome!)

合众达提供的两个驱动，可以添加自己的算法。一个是串口的，一个是实时系统的。(America to the two drivers, they can add their own algorithms. 1 serial port, a real-time system.)

串口调试工具，包含自动计算MODBUS crc校验码，是工具非源码(tiaoshi gongju)

RFID_VC++6.0源码_RFID读写 提供了RFID的开发源码，用VC编的，展示RFID卡如何加密，如何自毁。串口通讯支持RS-232(RS232)，RS-485(RS485)，波特率可选,RFID的天线可选，读卡频率可调。提供了控制RFID读卡功率的方法，功率从0至29可调，距离最大10米以上，该源码可用于交通、物流、运输、仓库管理、比条码技术强大。用于毕业论文答辩中，可以演示，程序看懂后，就对RFID整个工作原理较为了解。支持ISO18000和EPC_GEN2等类型的RFID卡。 VC++6.0的工作空间是“t1121.dsw”(RFID_VC++ 6.0 sources yard _ RFID read-write has provided the RFID exploitation source yard , used VC to weave, show how encrypted the RFID card , how to destructs self. String communication supports RS-232 (RS232) , RS-485 (RS485) , Porter lead may elect, the RFID air wire may elect , read card frequency adjustable. Method having provided the power controlling RFID reading a card, power is from 0 to 29 adjustable, )
