How to achieve the timing A contain timing B in the same block diagram?

Hi Jason,

usually DAQmxTiming is used after CreateTask/CreateChannels and before StartTask.

As is shown in the DAQmx example VIs coming with LabVIEW…

Hi GerdW,

But if I use the DAQmxTiming between channel and startTask, the timing won't influence the data in the loops. The data in the loops will run like crazy.

So how to do it to make the data in the loops run based on the DAQmxTiming? I am not sure about it. Can you give me some advice?

Thanks again!

Best,

Jason

Hi GerdW,

Thank you very much for your reply!

You get two bit streams (aka TTL signals) on two DO pins.

As they have a purpose/meaning you need to wire them (using real copper wire ) to your "clk pin of the chips", whatever that is…

For the two bit streams, I am still not very clear about :

1. how to generate the TTL signals cyclically to control the Timing settings?

2. My scanning part is only a dual-decoder with no clk pin and only the shift register of data part got clk pin for the TTL input. So how to input the two TTL with only one clk pin?

Thanks a lot!

Best,

Jason
