Source Code Control Using Mercurial in LabVIEW

Source code control is the major task in programming environment. Managing large of files with multiple developers is difficult because when people overwrite/modify the files in multi-user environment, it becomes difficult to track the changes. Here comes the use of configuration management. It can also be useful for small projects to get the previous versions. Various opensource and commercial source […]

Calibrating a Sensor in LabVIEW

Most of the LabVIEW applications involve data acquisition through NI hardware. Since we would be attempting to measure some real world phenomenon(like strain, load, pressure… etc), these will be converted into electrical signals(like voltage, current… etc) that can be measured using the data acquisition hardware. A sensor is a device which is used to convert a real world phenomenon into […]

Custom Control in LabVIEW

In LabVIEW, we have a set of built-in controls and indicators to use. We can also customize controls and indicators as per our requirement and save them to use in our applications. These can also be used as normal LabVIEW front panel object. I have selected push button for example. Customize the button by right clicking and select Advanced ->Customize. […]

ASCII code conversion

In LabVIEW when we interface with hardware, sometimes we have to send some control characters which will be sent using corresponding ASCII code. Type cast is the function which casts the input to the required data type. When input is string and the type to convert is U8 array, output will be the corresponding array of ASCII codes for each […]

Timer : Measuring Elapsed Time

Here you can find  a FGV timer implemented using  the function ‘Get Date/Time in Seconds’ to measure elapsed time. What is a Functional Global Variable(FGV)? A Functional Global Variable is a VI that uses loops with uninitialized shift registers to hold global data. Shift registers keep track of past information. So a FGV uses a For or While loop  to […]
