serial input read gives 10 samples but I only want 1

[brianNC]

I have my sensor connected to com1. Here is my code:

Private Sub CWButton1_ValueChanged(ByVal Value As Boolean)

Do While CWButton1.Value = True
Data = CWSerial1.Read
AllData = AllData + Data
TextIn.Text = AllData
CWGraph1.ChartY Val(Data)
DoEvents
Loop

End Sub

My problem is I just want one sample per loop, but I'm getting like 10. I don't know if I can change the output of the sensor. Is there a way to just get one sample at a time?

BTW I'm new with measurement studio, but it is very cool!

thanks,
Brian

Have you tried using the optional bufferSize parameter to CWSerial.Read? For more info, see the documentation for CWSerial.Read in the Measurement Studio reference.

I had the end of string set to "none", changed it to carriage return and that seemed to fix the problem.
