Generating PWM signal using Signal Express

[aamruth]

Hi,

   Would anyone help in generating PWM signal usinf Signal Express 2.5.1.   I am using a cDAQmx and connected NI 9472 to the slot number 6 to output the PWM signal. Also I have connected a NI 9421 to the slot number 5 to acquire the PWM signal, so that I could verify the signal.

   So would you please let me know how could I generate a PWM signal using Signal Express without any LabVIEW Programming. Please help me out.

HI Aamruth,

I atached a project, where you can see how to do it. I hope this helps.

Hii,

   Thank you for replying. I tried to check out the program you sent,however it not working and I am not getting a PWM wave. I also edited the program and tried some stuff but its also not working. So is their any other method to generate a PWM signal using this devices.

Hi,

of course you wont see a PWM, because you are counting only the edges.

If you want to SEE the signal, you have to program an analog input task and wire it then to the output of the counter. Then you should see the signal. Also important is  to add the singal to the display. There are only the added signals displayed.

I hope this helps...
