Arduino Uno will not appear in max

[keesc]

Hi,

I'm trying to communicate with my arduino uno through labview 2010 but when running any vi I keep getting Error 5005: Unable to find Arduino

When I check max my arduino does not appear, instead I see only 'no visa resources found'

My arduino drivers are installed and it appears just fine under my device manager. I've uploaded the firmware to the arduino (I've been told to use either LVIFA or LIFA and neither has worked). I've installed LIFA using VIPM without a problem.

Refreshing visa resources under max doesn't help, I keep getting '0xBFFF0011 (VI_ERROR_RSRC_NFOUND)'

Any help would be greatly appreciated - thanks

I've seen some people post that they had to re-install VISA.

Hey Keesc,

Can you try a simple Arduino example (printing stuff to the serial port and reading it from the Arduino serial monitor) to confirm that the COM port is working correctly?

If that works I would try using a VISA read example from the LV example finder to see if the LV and VISA are setup correctly.

Let us know what you find and we'll go from there.

Thanks,

Thanks for everyone's help, Nathan_B's suggestion worked. It turned out I had conflicting/redundant installations of VISA and that was most likely what caused it. I uninstalled them all then reinstalled the most recent edition and it's working now.
