When running the DualSource C# sample code after connecting to the device an exception is thrown.
This is due to a bug in the MainForm.cs. When the method void Connect(PvDeviceInfo aDI) tries to open the channels the exception, NullReferenceException, is thrown because the lSourceStreamChannel variable has a null value.
This bug can be fixed by replacing the line:
UInt16 lChannel = (UInt16)lSourceStreamChannel.Value;
with the line:
UInt16 lChannel = (UInt16)lEE.ValueInt;
When running the DualSource C++ sample code on Ubuntu a segmentation fault occurs. The reason is the same reason as C#.
This bug can be fixed by replacing the line:
lSourceStreamChannel->GetValue( lChannel );
with the line:
lEE->GetValue( lChannel );
Note:
The versions of the eBUS SDK affected by this bug in the C# DualSource sample code are: up to 6.2.8.
