Sparkette Posted March 30, 2009 Report Share Posted March 30, 2009 Is there any USB hardware compatible with LabVIEW which can let me get a taste of the hardware interfacing features in LabVIEW that I don't need to shell out hundreds of dollars for? There's got to be something in the sub-$50 price range which can be controlled by LabVIEW over USB. Any ideas? Quote Link to comment
Justin Reina Posted March 31, 2009 Report Share Posted March 31, 2009 Helo flarn, You can control any USB device with VISA (http://zone.ni.com/devzone/cda/tut/p/id/4478). Works the same as any other programming environment. -Justin oops posted too early ... If you take a look at the link, it is equivalent to any other bus IO in LabVIEW. Why do you want to take a trial of USB IO in LabVIEW? Seems like a lot of effort. Also, what kind of devices are you ultimately trying to interface, custom devices or commercial devices (i.e. a uC or a webcam)? Best of luck, -Justin Quote Link to comment
RalcoBe Posted March 31, 2009 Report Share Posted March 31, 2009 You can even do it for free. The soundcard, parallel and serial port are accessible in Labview, and can be used as I/O. For example, with the microphone input you can measure AC signals, like the speed af a car using the tacho signal Quote Link to comment

Some time ago I made simple metal detector and distance sensor using piece of copper wire and two jack plugs. I winded wire around a pencil making a coil and was generating sinusoindal signal through headphones output and measuring responce with microphone input. There is also a number of cheap "osciloscope cards" working with sound card (around few $) - making such a play safer for sound card Quote Link to comment
ASTDan Posted March 31, 2009 Report Share Posted March 31, 2009 If all you want to do is get a feel for the daqmx api I would recommend creating simulated channels in daqmx https://www.ni.com/pdf/labview/us/acquiring-data.pdf Quote Link to comment
Justin Reina Posted March 31, 2009 Report Share Posted March 31, 2009 Good call on the simulated daqmx tasks. Also look at the TCP/IP and UDP examples in the NI ExampleFinder. Those can provide hours upon hours of fun and amusement . -Jusitn Quote Link to comment
Phillip Brooks Posted March 31, 2009 Report Share Posted March 31, 2009 Under $50 is probably pushing the limits. Consider spending ~ $100, and there are a couple of options: LabJack iUSBDAQ Quote Link to comment
wesramm Posted April 11, 2009 Report Share Posted April 11, 2009 LabJack is the way to go for this price point. Check out the U3 or U12. http://www.labjack.com Wes Quote Link to comment
