Hi. I am testing my NI MyDAQ for the EMG monitor I downloaded from this community. And the error stated above occurs. What is the solution in this problem? Thank you.
The Device Identifier is invalid. If we saw the code (attach a VI, not a picture, please), we might be able to tell you how to fix this ...
Hello. This is the VI that I have downloaded in this site, also there are no .png images attached on the zip file. Can you also help me with that? Thank you
there is no VI, no PNG and no ZIP (and not even a link)!
Hi. I'm sorry, https://decibel.ni.com/content/docs/DOC-25987#comment-51398 this is the link for the myEMG monitor I am trying to modify. I uploaded the VI but seems it wasn't. Try to go on the link so you can try the emg monitor and can identify the problem. Thanks, Godbless.
unfortunately I don't have the needed BiomedicalToolkit installed, so I cannot check the settings in all those ExpressVIs and missing functions…
From plot names I guess the original author had a device named "myDAQ1" - do you use the same?
I suspect that GerdW (and I) has identified the problem you are having. You use an Express VI to take the data from your MyDAQ. It wants to "talk to" a specific named device, and if it doesn't "see" a device by that name, it will throw the Error you encountered.
Thank you for all your help, I'll try to do your suggested solutions. I'll keep you posted.
