pc到PLC的串口通讯程序源码 有详细的注释

这是一个综合了多种通信方式(RS232串口/TCP/UDP/E1)的通信接口类,它对外提供了统一的接口,使得开发人员不再需要关心通信编程的细节! 内部使用多线程,效率极高,并且经过了2年的使用,不断的得到维护,目前最新版本.-This is a combination of various means of communication (RS232 serial/TCP/UDP/E1) Communication Interface category, which offer a unified interface that allows developers no longer need to care about the details of the Communication Programming! The internal use of multithreading and efficient way, and after two years the use of continuously maintained that the latest version.

ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels. Lenient thresholds give high sensitivity but low specificity, strict thresholds give high specificity but low sensitivity the ROC curve plots this trade-off over a range of thresholds (usually with sens vs 1-spec, but I prefer sens vs spec this code gives you the option). It is theoretically possible to operate anywhere on the convex hull of an ROC curve, so this is plotted too. The area under the curve (AUC) for a ROC plot is a measure of overall accuracy, and the area under the ROCCH is a kind of upper bound on what might be achievable with a weighted combination of differently thresholded results from the given classifier -ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels. Lenient thresholds give high sensitivity but

近日从网上下载一VB实现异步串口通讯的文章,很实用,特与大家共享.-recently downloaded from the Internet a VB asynchronous serial communication articles very useful, especially to share with you.

编程板：读取 SD 卡是否有“Can_Updata.bin”文件，若存在文件，则从 CAN 总线发送 一个“UPDATA”信息，等待目标板返回“OK”信息，后读取文件内容，发送头八个字节 即应用程序的 MSP 和中断向量起始地址，等待目标板返回“BEGIN”信息，接着继续从文 件头开始读 1024 个字节，并通过 CAN 总线发送给目标板，等待目标板返回“CONTINUE” 信号，接着发送 1024个字节，直到读到文件尾部，即读出的字符个数小于 1024个字节， 发 送最后读出的字符并发送，后发送“STOP”标记，应用程序发送完成。 目标板：复位开发板读取后备寄存器 BKP_DR1==0x55AA 是否成立，若成立则等待编 程板发送“UPDATA”信息，随后返回“OK” ，等待编程板发送一次数据，返回“BEGIN” ， 开始接收编程板的 1024 个字节后返回“CONTINUE” ，继续接收，当接收到 2048个字节后 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

matlab仿真的TD－WCDMA源码，比较不错的-matlab simulation of the TD-WCDMA source, compare well

In this simulink model , baseband 8-ary PAM detection is simulated .A half-sine pulse shaped PAM signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The 8-ary PAM signal transmitted is recovered at the detector output.

turbo码的编译码实现，很全，还是没有画图语句，自己补充-turbo code codec implementation, it is full, or not drawing statement, added their own

因特殊的业务需要，某些电话交流需要在第三方的监视下进行，假定某电话交流由甲乙丙三方发起，丙为监听控制方，当甲开始说话时，丙可以不允许乙听，并且开始录音，当甲说完时，丙确定是否可以让乙听，如可以。给乙放录音，当乙说话时，重复以上操作。-because of special operational needs, some telephone exchanges in the surveillance of third parties under the assumption that a telephone exchange was launched by the tripartite B, and C to monitor the controlling party, began to speak when the A, B C can not listen, and began recording at the end when A and C to determine whether or not they can B listen, if we can. B recordings to release, when the B words, to repeat the operation.
