Cannot generate a trigger on the RTSI or PXIe_Trig lines using the 5641R

Hello,

 

I'm trying to use the bus trigger lines on the 5641R to generate a trigger on the RTSI (PXIe_Trig) lines for another measurement device. I've created a simple FPGA VI that generates a trigger periodically and sets the trigger line to true after enabling the line for output. When I compile this for the 5641R, no trigger occurs on the line and my measurement device never acquires any data.

 

As a sanity check, I also compiled this code for the 7965R FlexRIO and it was able to generate the triggers as expected.

 

I've attached a screen shot of the compiled code. In addition to this setup, I've also changed the trigger routing in MAX to route the signals out from the middle (triggers originate from Bus 2 and go to Bus 1 and Bus 3). From what I've read, this should work, and as mentioned above, it does on the FlexRIO. Any suggestions or ideas?

 

Thanks,

Gary

Hi,

I don't understand why you use this feedback node: your value is never equal to 0 so you can't generate the trigger.
