Blackfin Processor HMI Limitations

[RDD]

I have developed a user interface using Labview 8.6 on a new machine vision application using 4 GigE cameras.  The next step would be to move to an embedded design to save space for multiple machine interfaces. I display all four camera interfaces and a lot of user controls for data display.  Is there a place in the NI documentation on the Blackfin Embedded Module that discusses limitations on how much the Blackfin can handle for a user HMI interface?

Thanks,

Doug

Hi Doug,

We don't have any user interface limitation specs in the LabVIEW Embedded for Blackfin Module, because it's not going to be limited by the software. How intensive your UI can get is going to be based on factors like CPU, RAM, JTAG or ethernet throughput, etc. So, you'll have to identify what's going to bottleneck your UI updates. The board which comes with the Blackfin Module is the BF357; it's manual is here on Analog Devices website: http://www.cs.uml.edu/~fredm/courses/91.548-spr06/files/195925639ADSP_BF536_7_pre.pdf

Good luck, and let me know if I can help any further!

The blackfin BF548 eval kit with display is very powerfull with displaying images in inherent visual DSP code (looking at the demo code that runs on bootup).  However, the LV interface does not support images (bmp, jpg, etc) on the front panel.  The LV code would have to render these images from the dev environment to the blackfin display.  Don't get me wrong, the LV capabilities to create a GUI are very good compared to creating one in VisualDSP (not that I have tried, nor do I want to try)...

Thanks LaRisa and Joe for your help.
