use a USB to RS485 module, with twisted pair of the Development Board and the module A and B respectively connected together, the USB plug into the computer, and then you can communicate. After learning the 13th chapter practical serial communication method and program, do this serial communication method is very simple, the basic is consistent. We use the idea of a practical serial communication routine, do a simple

The first program of the Line Segment treeThe problem is that N line segments are now known, and the endpoint is input to you in turn, and then there are m inquiries. Each query enters a point, which indicates the number of line segments on which the point has appeared;The data volume may be large. For example, if ther

When compiling the MFC program, I want to print the debugging information. After using cout, I found that the program did not automatically pop up the command line window as I imagined, and there was no place to view the output information. Baidu knows to manually call up the command line window to view the output info

Sometimes we want the form program to accept command-line arguments and run it as a console. But it takes a little skill to make it happen. If you are doing a WPF program, write such a statement in the loaded event of window: Console.WriteLine ("Hello word."); Then run it from CMD. You will find that the statement has no output at all. As shown in Figure 1.

1. Usually when we write programs in Pycharm, we write #!/usr/bin/env python on the first line.Such as:#！ /usr/bin/env Python3#-*-coding:utf-8-*-#Author xiaoxingPrint ("Hello world!")The purpose here is to tell the operating system to invoke the Python interpreter when executing this script, in addition to preventing the operating system user from not loading python into the default /usr/bin path. When the system sees this line, it will first find th

One, executable scriptLet's start with the simplest of words.First, using the JavaScript language, write an executable script hello.#!/usr/bin/env nodeConsole.log (' Hello World ');Then, modify the permission for Hello.$ chmod 755 HelloNow, hello is ready to execute.$./helloHello WorldIf you want to remove the path in front of Hello, you can add the path of hello to the environment variable path. Another better approach, however, is to create a new Package.json in the current directory and write

Process has been available for a long time, but I did not pay attention to it. For example, call a command line: "cmd/c dir c: \ winnt"; put the result in a string.ProcessStartInfo psi = new ProcessStartInfo ("cmd", "/c dir c: \ winnt "); Psi. RedirectStandardOutput = true; Psi. UseShellExecute = false; Process p = Process. Start (psi ); Output = p. StandardOutput. ReadToEnd (); P.
