Issue Details

I use NI 7935R and NI 5734 adapter module to build a FM radio monitor system. And I'm using the Stream IDL to stream FM spectrum data from the FPGA target to the host, following the programming example of Stream IDL as shown in Figure 1.
 


Figure 1.


After running the VIs for a while, error -1074100508 occurrs, which is described as followed.

Error -1074100508 occurred at niInstr Streaming v1 Host.lvlib:Wait for Stream.vi:2620004

How can I fix this error?
 

Solution

The error -1074100508 occurred at the "Wait for Stream.vi" in the host VI. To fix it, you can use "Get Stream Samples Transferred.vi" and "Get Stream State.vi" to replace "Wait for Stream.vi". Find Figure 2 for detailed codes.
