can't see COM port

[skunkwerk]

Hi,

   I'm trying to read in serial data from an Arduino Uno board that's connected via USB on Windows.  I have the driver installed, and the Device Manager in Control Panel shows an "Arduino UNO (COM3)" listed under Ports (COM & LPT).  Furthermore, the serial monitor in the Arduino software is succesfully displaying values read from the board.

   However, when I tried using the sample VI posted here (serial_arduino3.vi):

http://ni.i.lithium.com/t5/LabVIEW/Writing-terminal-COM-data-to-graph-using-Visa/m-p/1511430

I could not change the COM port in the front panel - only COM1 was listed, and when I clicked on "Refresh" nothing happened.

any suggestions?

thanks,

imran

Can you see it in max? Also have you just tried typing com3 into the control?

Hey Steve,

   i've fixed the issue - it turns out I hadn't installed the NI VISA drivers, and vmware was causing all sorts of USB weirdness.

thanks!
