Synchronizing Multiple Waveform Graphs

[Mullenix]

I'm sending some data generated in LabVIEW 7.0 to a 'C6701 DSP using the TI DSP Integration Toolkit. I then process the data and send the results back to LabVIEW for display purposes. I am noticing, however, that the waveform display of the input leads the output waveform by a good bit (Meaning that by the time the output waveform is displaying, the input waveform has already updated to a new set of data). This is causing a number of problems. How can I have both of the waveforms update at the same time?

Hi,

You can use a wait function and find a suitable wait time before you display your input data. In the meantime, the data gets processed and output waveform is displayed almost at the same time as input waveform. A much better option would be to use two shift registers to store the input and output data and display them on the next run of the loop.
