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

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

connectScalar(app.hInst,app.TextArea,'data','callback',(t,d)string(d));

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));
