LED Indicator

[Naveen654]

Sorry, I keep hitting space bar...

I'm using LabWindows/CVI and put a LED to act as an indicator. 

I am generating a discrete pulse and I want the indicator to turn on when it is outputing my waveform.  I have a "Generate" button to initiate the pulse.

I put the indicator lines in the Callback function for the Generate button.  It goes something like this:

if(event == EVENT_COMMIT)

{

  SetCtrlVal(panel, AO_PANEL_LED_2, 1);

  for(i=0; i<300, i++) //updating 300

     AO_VWrite(1,1,waveir[i]); 

}

SetCtrlVal(panel, AO_PANEL_LED_2,0);

I am assuming that the indicator to turn on is 1 and the indicator to turn off is 0.  Is this correct?

Yes, your assumption is correct, but you may need a ProcessDrawEvents () to update the panel before entering the for loop, otherwise your led won't light.

THANKS!  WIthout the function it wasn't working, but I added it and it appears to work great!
