You can check more details about this project by clicking on this link: Remote monitoring system using Arduino and Xbee. This project is called remote monitoring system using Labview and Zigbee. I have already posted a project on labview with arduino for getting different sensors data on labview. Today I am going to start a series of tutorials on Arduino interfacing with Labview. The image below demonstrate how a Power Supply driver running in its own thread within a Symplify™ application can free up to 50% of available CPU time that would normally be lost if the communication with the power supply was done sequentially with other actions such as datalogging and supervisory functions.Hi Everyone, I hope you are good and doing well in your life.
NI invests a lot of time and effort to make sure that the driver support high throughput, low-latency and offer very meaningful information upon a software exception. This is pretty much the same concept that we are presenting here and it is one of the many benefits of using NI hardware and drivers. A lot of the work completed by those drivers is actually done in the background rather than sequentially when the VIs are called. There are higher quality drivers such as NI DAQmx. Those drivers can then leverage the manufacturer’s VI and LabVIEW will make sure that other code can be executed during long wait periods in between commands (or while waiting for a measurement.) Standard Palette for a serial DMM instrumentĮach VI can also presents a simple User Interface which exposes many more options available from the instruments but were not exposed to the user. Communication through CVT allows various processing rates The interface (or API) to each driver becomes specific Tags which allows proper encapsulation and protection of their “private data”. This typically requires more development but the existing core libraries within our platform makes this operation very easy. This is what we consider as “ Symplify™ drivers”.
The solution to this is making sure that all this code executes in different threads. This is especially true for Serial Instruments (COM port): with 2 or 3 of those instruments, a standard application with sequential execution can be reduced to 1Hz or slower due to the long wait time in between commands. Many necessary delays can slow down other sequential code However, many of those calls tend to be “blocking” (Send command, Wait, Read results) to be easier to use by the programmer at the expense of the end user’s test plan. Those tend to be a very good starting point to quickly communicate with their equipment to change setpoints and readback measurements but they are often Application Programming Interface (API). Equipment manufacturers often make LabVIEW “drivers” available for download on their website.
