NO data on MOSI pin! (SPI transfer)

[ACarpio]

Hi,

      I program a VI to transfer data via SPI Module. I choice DMA mode! I run the VI and I have the clock signal (SCK) but I do not have any signal or data on pin MOSI. I think the problem is with the buffer but I read de help file and I can see what is the problem.  This is the via. Please if anybody can say what I do wrong?

thanks!

I assume this question is regarding the NI USB-8451. Please post your question in either the LabVIEW or Instrument Control forums.

Hi,

Oh, well you are in the right place then

I am investigating your question and I will let you know what I find out.

Hi,

Main1.vi has been modified to continuously output data. The values you enter in the array control will output on MOSI. Let me know if you have any questions.
