3. Scroll down to move the cursor inside the click event handler of the
button control.
4. Add the following code to read a raw data point from a specified
channel on the Measurement Computing device, convert the data to
volts, and display the value on the meter.
[VB.NET]
'Set channel, range, raw value, and volt variables.
Dim Channel As Integer = 0
Dim Range As MccDaq.Range = MccDaq.Range.Bip10Volts
Dim RawValue As Integer = 0
Dim Volts As Double = 0.0F
' Perform analog input operation with Measurement Computing board,
' channel, and range, and return raw value.
DaqBoard.AIn(Channel, Range, RawValue)
' Convert raw value to engineering units.
DaqBoard.ToEngUnits(Range, RawValue, Volts)
' Display value on meter.
Meter1.Value = Volts
[C#]
// Set channel, range, raw value, and volt variables.
int channel = 0;
MccDaq.Range range =MccDaq.Range.Bip10Volts;
ushort rawValue =0;
float volts =0.0f;
// Perform analog input operation with Measurement Computing board,
/// channel, and range, and return raw value.
daqBoard.AIn(channel, range, out rawValue);
// Convert raw value to engineering units.
daqBoard.ToEngUnits(range, rawValue, out volts);
// Display value on meter.
meter1.Value =volts;
