labview embedded

[cwolfskill]

Hi,

I am interested in using LabView embedded on the Blackfin, and was wondering about the different capabilities of the embedded version of LabView.  Specifically, how many different threads can be run simlutaneously using LabView embedded?  (I would possibly be needing 3-5 threads.)  Also, does it have all the toolkits that the full version of LabView has?  I would like to use it to perform image recognition and closed loop feedback control. 

Thanks in advance for your help with this question.

Hi Christina,

The maximum number of threads allowed to run on the Blackfin is selectable, and spawning 5 threads is not uncommon.  The maximum amount that the processor can handle within your timing limits depends on the processing demands of each thread.

In terms of the toolkits available for use on the Blackfin, not every toolkit designed for Windows will be able to run on the Blackfin.  Common reasons why a toolkit will not run on a Blackfin are that it depends on Windows-specific functionality (like the Report Generation for Microsoft Office or Database Connectivity toolkits, since they use ActiveX) or uses VI's and functions that are unsupported for the Blackfin.

For closed-loop control, the Simulation Module and PID toolkit have been shown to work and you can of course implement your own algorithms.  I don't believe our IMAQ libraries have been tested on the Blackfin target, so you may have to implement your own image processing routines.

If you have additional questions about Blackfin or LabVIEW for embedded applications, let us know!  (and don't forget - we have a dedicated discussion forum board for LabVIEW Embedded where you can find yet more information and other users who are working with the product)
