LabVIEW VI Front Panel-EEWORLD

　　Select "New VI" in the startup window to enter the virtual instrument VI programming environment. The appearance and operation of virtual instrument programs imitate real instruments, such as oscilloscopes and multimeters. Each VI uses functions to obtain information input from the user interface or other means, and then displays or transmits the information to other files or computers.

　　The VI program in LabVIEW consists of three parts: the front panel, the flowchart, and the VI icon/connector panel. The front panel is the user interface of the VI program and the interactive input and output port of the VI program. Input controls and display controls are usually used to create the front panel. Input controls refer to input devices such as knobs, buttons, and dials. Input controls simulate the input devices of instruments and provide data for the VI flowchart; display controls refer to display devices such as charts and indicator lights. Display controls simulate the output devices of instruments and are used to display data obtained or generated by the flowchart. The blank front panel window is shown in Figure 1.

Converting strings to ASCII in LabVIEW

Because I want to make a chart after collecting any data, I wrote a serial port program in LabVIEW, but the output is a string, and the input data for drawing must be a numeric type. I searched all the controls but couldn't find a control that converts the string into the corresponding ASCII code. So I searched online,

LabVIEW Case Structure

When the LabVIEW conditional structure displays 0, 1, 2, 3, if the preceding output is a digital type, then 0 is true (all assumptions are not true), 1 is the first case, 2 is the second, 2^2 (4) is the third, and 2^3 (8) is the fourth.

LabVIEW loop structure data channel and automatic indexing

　　The loop structure data channel is the only way for data inside the loop structure to exchange (input/output) data with data outside the structure. It is located on the loop structure frame and displayed as a small square. Figure 1 and Figure 2 show the data channels of the For loop structure and the While loop struc

Summary of Labview operation basics

Through the mind map, I will briefly summarize some of the operational knowledge I have learned recently in Labview . The first is the creation of VI . This part can be operated by the mouse, but there is a relatively simple shortcut key combination. Saving VI also has a mouse click operation and a cor

A low-cost LabVIEW experimental teaching system based on MCS51

NI proposed the concept of virtual instruments in the 1970s. Virtual instruments are computer instrument systems designed by users on a computer-based platform, with virtual panels and software to implement test functions. They are the product of the combination of computers and test instruments. The most commonly use
