Reads from analog inputs immediately, returning raw A/D converter values.
Namespace:

Syntax
Visual Basic (Declaration) |
---|
Public Sub ReadAnalogCodes ( _
channels As Integer(), _
values As Integer() _
) |
C# |
---|
public void ReadAnalogCodes(
int[] channels,

function readAnalogCodes(channels, values); |
Parameters
- channels
- Type: array<
System..::.Int32
>[]()[]
An array containing the numbers of the analog input channels to be read.
Channel numbers are zero-based. Thus, channel 0 is the first channel, channel 1 the second channel, etc.
Select a board type from the list for board-specific details:
.
- values
- Type: array<
System..::.Int32
>[]()[]
An array for receiving the raw A/D converter values read from the analog inputs. Each element in
the values array corresponds to the same element in the channels array.
Hence, there must be as many elements in the values array as there are channels.
Remarks
Examples
This example illustrates how to read analog inputs immediately, as raw A/D converter values. It reads analog channels 0-3.
Exceptions are ignored for simplicity.
C# | Copy Code |
---|
int [] channels = { 0, 1, 2, 3 };
int [] buffer = new int [channels.Length];
card.ReadAnalogCodes(channels, buffer);
|
Visual Basic | Copy Code |
---|
Dim channels() As Integer = {0, 1, 2, 3}
Dim buffer(channels.Length - 1) As Integer
card.ReadAnalogCodes(channels, buffer)
|
Visual C++ | Copy Code |
---|
array<int>^ channels = { 0, 1, 2, 3 };
array<int>^ buffer = gcnew array<int>(channels->Length);
card->ReadAnalogCodes(channels, buffer);

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