Follow along with this step-by-step tutorial to make a "hello, world!"-like application to experience the advantages of multiple linked VIs running simultaneously on the real-time (RT) target and desktop computer: (1) "RT Main" runs as the RT target start-up VI, blinks the onboard LEDs, and reads the onboard button; these onboard devices physically connect to the FPGA I/O pins which are accessed with the Academic RIO Device Toolkit Express VIs and default FPGA personality, and (2) "PC Main" VI runs on the desktop computer as a user-friendly human-machine interface (HMI) for remote command and control of "RT Main" through the network via shared variables hosted on the RT target.
See the "RIO Developer Essentials Guide for Academia" available at learn-cf.ni.com/teach/riodevg... for more video tutorials related to programming, architecting, and networking with LabVIEW and NI Academic RIO products.

Thank you. Exercises the fundamental principle developing crio app.

First a big thank you for all your content. Second, a recommendation. Include some guidance on “auto-deploy shared variables” getting in the way of connecting to the RT target that is running the startup VI.

Thank you for demonstrating the 'how' so clearly. Very helpful! What is the advantage of having all indicators and controls in a separate VI on the host pc? Is it purely more CPU efficient? Could you live with keeping indicators and controls on the RT target VI?

Thank you very much Sir for such a nice demonstration

@gazpacho59 3 года назад

Nicely done - very helpful. If you don't mind my asking, what software did you use to screen-capture and record the video? I particularly liked how the cursor was always easy to find, and it was obvious when you clicked on things.

why are the variables able to react in the PC main VI when they are outside the while loop?

@armanmanukyan1970 5 лет назад

When PC Main starts running, all controls and indicators on that VI serve as binding between themselves and shared variables on RT target, and loop on PC Main merely runs idle,waiting for the stop button to be pushed, thus reducing the usage of the CPU.

Please answer me, is it possible to run this example without having any myRIO device at hand.I doesn't find any example in the Internet without NI devices, for trying at home on my own PC.Thanks

Yes, you can by changing the FPGA Target mode

Hi, I don't know what I'm doing wrong... But at Step 5, when I run as startup "My Real-Time Application" and then I want to open "PC Main", it shows me this advice: "The target is already running a Real-Time Startup Application. Press OK to confirm you want to abort the existing application and connect to the target from this project." I can't hit run as you do in 24:00 min. Do you know why it happens? Thank you in advance.

This related video talks about deploying a start-up application in more detail, perhaps it can help: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JXoJECRS-eo.html
