Labview Embedded with ADSP-BF537

[Eman2334]

Hi,

I am currently working with the ADSP-BF537, and i am trying to communicate with the SPI bus. However, I am having trouble with reading the data from the MOSI line. When placing a scope on the data line, I can see the response. However, when reading in my VI, the data buffer returns empty. Is there a special order for the read and write, or do I have to specify one as an interupt VI to ensure it executes? Any help would be greatly appreciated.

Thanks!

Hi Morgan,

I’m not sure exactly what you are running into but it sounds like you just need an example of how someone has set up the SPI and got it working. The best example to look at in the LabVIEW Example finder is titled “SPI and UART.lvproj.” Dig though the SPI VIs and see what goes into setting them up.
