generqte a PWM signal with LabVIEW using digitals outputs
I have checked out, Device 1 is the correct nomber for the 6070E installed on my computer. I looked at the error codes, but it didn't help me more.
I 'll try to uninstall all and install the new version you gave me. Thanks again, I'll tell you on monday if it's worked.

hi i2dx
I am installing the last NI-DAQmx version, however, it's important for me to know if the same PMW signal is feasible with tradional DAQ VIs.
thanks

yes, it is possible to programm the PWM with traditional DAQ, but I would not recommend it, anyway!

if the device is in the PXI, you have to switch your traget to the PXI-System and work with the RT-Module ...

i have tested it with a M-Series NI-PCI-6251,
i used LV 7.1 for this example ...

generqte a PWM signal with LabVIEW using digitals outputs
Hi i2dx, it's me again.
Last time, I had told you I had an error (-200077) and I found what was the problem : your program can't work with my 6070E because, I have found a exemple in LabVIEW (Cont Write Dig Port-Ext Clk.vi) with use the same VI as your program, and I get the same error. I ckecked out, the 6251 card that you used is in the list of hardware compatible with the exemple, but not the 6070E card. So I have to find another solution to generate a PWM signal to the DO line. I would like to know if you think that I can use the exemple "Write Dig Chan.vi" in replacing "Data to write" by a waveform which will be a PWM signal waveform and how can I do that ?
Thanks

sorry, but this wont help.
take a look at the specifications of the card and you will see, that the PXI 6070E is only capable of 50 Hz DIO Input / Output.
And the write Single Chanel Solution will be slower, because it's software timed and you get an maximum resolution of 1 kHz, but it's not recommended to use software timing at this "high" sample rates anyway.
it seems, that you are not able to get this running with your card. The new M-Series DAQ-Boards are capable of 10 MHz DIO operations ... maybe you should contact your local NI sales representative?
