I have been struggling all week on how to pass data to and from a 2D array of clusters from LabVIEW using the TestStand API via Callbacks.
I couldn't find anything online, but the AEs finally figured it out for me. So, I thought I'd post how I did it.
If you use the GetPropertyObjectByOffset method, you can address a 2D array element by the offset. In TestStand, even though the array elements are a matrix, they are stored in memory contiguously. The offset to access an individual element is calculated by using the following formula:
[x],[y], totalX
offset = y*totalX + x
I am using StationGlobals for my array, so in order to make this work, you first use the SequenceContext to locate the StationGlobals Property. Attached is an example.
