cdma钟卡控制编程,用到口通讯,数据包拆分组合,发送

基于51的串口通信程序！！希望大家有用！-51 Based on the serial communication program! ! I hope everyone useful!

从串口读取，并解析NMEA格式的GPS数据的程序。将解析后的数据显示到界面上。需要和发送端的程序配合使用。-read from the serial port and analytic NMEA GPS data formats procedures. Analysis of the data shows that the interface. Needs and transmitter used in conjunction with the procedure.

上传个考勤系统,希望别人也能用.该代码只能算初级的东东,软件代码复用性不高,重复代码比较多.唯一感觉有点取鉴的可能就是端口和dll的连接,还有线程的使用,本想改一改,但是手头没有考勤机了,对应考勤机是890C的.-From a performance appraisal system, I hope others can use. The code can only count the primary Dongdong, software, code reusability is not high, repeat the code more. The only feeling a little check Kam is probably dll ports and connections, There are threads to use, simply wanted to, but do not have attendance machine, and the corresponding attendance machine is the 890C.

实现51单片机的串口通信。可通过超级终端调试。-51 Singlechip realize serial communication. Debugging through HyperTerminal.

是一个串口通信的程序,本人前段时间做的一个项目.-is a serial communication procedure, I do a side project.

是关于金电电源通信规约的串口通信程序，功能是把电源监控器的采集数据上送到规约前置机中。-GOLD comunication rule

从串口读取数据，有两种方法，1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的接收，其实就是第一种方法的变种： 一个侦听EV_RXCHAR,一个对EV_RXCHAR进行分析，其实就是超时判断。如果接收到一个消息后，一段时间没收到下一个EV_RXCHAR，就认为是一个数据包的结束。这个线程就会通知数据接收线程，进行数据接收。一般同一包数据，两个字符之间的时间间隔，应该很小了吧，而两个数据包之间的间隔，应该不会太小吧！（这个地方我不清楚，猜的:( :) ）最后一个线程，是接收数据的。-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data reception, the first method is a variant : an interception EV_RXCHAR, one pair of EV_RXCHAR analys

基于RS－232的，对多路转换开关的控制程序，希望对大家有用！^_^-based on RS-232, for multi-channel switch control procedures in the hope that it may be useful right! ^ _ ^

USB便携式多通道分析仪的ＰＣ端软件，可以实现对采集信息的频谱分析，并且获得频谱图以及相关数据，具有极高的价值．欢迎大家下载与交流！-USB portable multi-channel analyzer software on the PC can be achieved on the information collected spectrum analysis, given a spectrum of related data with a high value. You are welcome to download and exchange!
