Syntax
Visual Basic (Declaration) |
---|
Public Sub WriteAnalog ( _
channels As Integer(), _
voltages As Double() _
) |
C# |
---|
public void WriteAnalog(
int[] channels,
double[] voltages
) |
Visual C++ |

public:
void WriteAnalog(
array<int>^ channels,
array<double>^ voltages
) |
JavaScript |
---|
function writeAnalog(channels, voltages); |
Parameters
- channels
- Type: array<
System..::.Int32
>[]()[]
An array containing the numbers of the analog output channels to be written.
Channel numbers are zero-based. Thus, channel 0 is the first channel, channel 1 the second channel, etc.
Select a board type to the list for board-specific details:
.
- voltages
- Type: array<
System..::.Double
>[]()[]
An array containing the voltage values to write to the analog outputs. Each element in
the voltages array corresponds to the same element in the channels array.
Hence, there must be as many elements in the voltages array as there are channels.
Remarks
Examples
This example illustrates how to write analog outputs immediately. It writes 0.5V, 1.5V
2.5V and 3.5V to analog channels 0-3 respectively.
Exceptions are ignored for simplicity.
C# | Copy Code |
---|
int [] channels = { 0, 1, 2, 3 };
double [] buffer = { 0.5, 1.5, 2.5, 3.5 };
card.WriteAnalog(channels, buffer);

Visual Basic | Copy Code |
---|
Dim channels() As Integer = {0, 1, 2, 3}
Dim buffer() As Double = {0.5, 1.5, 2.5, 3.5}
card.WriteAnalog(channels, buffer)

Visual C++ | Copy Code |
---|
array<int>^ channels = { 0, 1, 2, 3 };
array<double>^ buffer = { 0.5, 1.5, 2.5, 3.5 };
card->WriteAnalog(channels, buffer);

Exceptions
Exception | Condition |
---|
Quanser.Hardware..::.HilException |
If the write cannot be performed then an exception is thrown. This situtation
typically arises if the board does not support analog outputs or the hardware
resources required are in use by a task.
