PicoScope Streaming mode

Postby Adel_Labview » Tue Jun 07, 2016 10:46 am

Hi everyone,

The oscilloscope I'm using is PicoScope (4424), i use it with Labview 2014 and the example for streaming, all work fine :) . i´m trying now to use the Labview producer consumer state machine, but i don´t know why there is no data in my (streming-array).

Any help would be great,

Thanks
Adel

Hi Adel,

Apologies for the delay in someone posting back in response.

This could be due to the reference to the buffers being passed to the drivers being lost so you may need to use the Data Value Reference Node to keep these in memory.

The other thing that I noticed is that you do not have an inner loop to poll the GetStreamingLatestValues sub-vi as per the streaming example.

Once you have started the oscilloscope streaming, you need to call the GetStreamingLatestValues sub-vi in a loop until your data collection is complete or you wish to stop data collection.

Hope this helps,
