How to stream vector (1X5) data from Target device to App designer?

3 views (last 30 days)
I have been using ConnectScaler object function to stream data to app desginer from Speedgoat. but I am unable to stream vector data .
I tried Converting to string in App designer but it is not working.
ConnectScaler(app.hInst,app.TextArea,'data');
Unable to resolve the name 'app.hInst'.
ConnectScaler(app.hInst,string(app.TextArea),'data'); // not working
I tried to introduce matlab function in simulation to convert into string, but no progress.
y=string(u); // unable to generate code

Hi Jesica,
I think there are several mistakes here:
  1. The correct syntax of the function is connectScalar (lowercase "c" and "a" before "r")
  2. Is the object app.hInst initialized/declared in your app before you use it in the connectScalar function? You can for example declare is as a private property in your app.
  3. What type of component is the app.TextArea object in your app?
I hope this is helpful!

Thank you for your answer.
  1. Its typo. I had corrected and still it was not wokring.
2. app.hInst is Instrument object created to stream data from target computer to development computer. i had defined it.
3. app.TextArea is a object used to display string in app designer.
4. I solved the issue by using the below command.
connectScalar(app.hInst,app.TextArea,'data','callback',(t,d)string(d));
