Multifunction DAQ
May I ask how to generate a clock signal using NI USB-6210 at PFI?
Hi, bluesky08.
When you download the DAQmx driver, you will also install example programs for your application development environment (ADE). For example, if you're using LabVIEW, these examples can be found in the LabVIEW Example Finder by selecting Help»Find Examples from the toolbar. Navigate through the following folders: Hardware Input and Output»DAQmx»Generate Digital Pulses and open the Gen Dig Pulse Train-Continuous.vi. This example is also installed for other ADEs. If you are not using LabVIEW and have difficulty locating this example, respond back to this post requesting the example location. In this particular example, you will be generating a pulse train of selected frequency and duty cycle on one of your counter outputs. For the USB-6210, ctr0 output will be on PFI 4 and ctr1 output will be on PFI 5. This information can be found on the NI USB-6210 page of the DAQmx Help:
If you would rather output the pulse train on a different PFI line, you will need to define this PFI line with the CO.Pulse.Term Channel Property node. More information and a great example of this can be found at the following DevZone: http://zone.ni.com/devzone/cda/epd/p/id/4422
Let me know if you need any more information. I hope you're having a great day!
