Hi. I just started using LabVIEW and I am currently using NI LabVIEW 2013 to control a quadcopter by using keyboard. I can only use certain buttons on my keyboard to toggle the buttons. Is there a way for me to for example use letters "w/a/s/d" to control my buttons?
Thank you 🙂

Use an event structure to detect the Key down and key up events. Look at what key is pressed by the event data node inside the event case.

I found the example but I think it wasn't useful for me.. I've attached my vi for lv12.

Example for getting the keys pressed with events.

Use Raloks event structure, then just add a case structure for the different keys.
Remember chars are: w,s,d,f,g,h,j,k,l...............
vkeys are: Up, Down, Ctrl, Return...............

Please keep timeout for event structure, otherwise when no key is pressed and you try to stop the vi, it will not stop.
Ideally, the Stop button should have a value change event case in the structure to handle that.
