Followed toolkit instructions but still no response on arduino uno

[physicsnut_12]

Hi everyone,

I am an undergrad and we were going to use the arduino to get real time feed back in an experiment. I installed LV 2011 and Arduino 1.0.1 on my computer followed by NI- VISA and JKI's VI Manager. I downloaded the LVIFA file and installed the firmware onto the arduino as instructed. I attempted to use the simple LED example to test and make sure everything was working but I got no response from the LED when switching the value from 0 to 1. I did some looking and found numerous things referring to different things to check. I have set the baud rate to 115200 for my COM6 port for the arduino as well as checked in the VISA and Measurements and Automation. Both are able to detect the arduino. But in LabView I cannot seem to get it to work!!! Any thoughts or advice would be appreciated.

Two possibiities might be causing your probelem  One, are you using the newer Arduino Leonardo board?   LIFA will not work with an Arduino Leonardo.  The LIFA firmware needs to be updated to support an Arduino Leonardo.  Two, try going back to the 1.0 version of Arduino software.  1.0 is the version of the Arduino sofware all the examples were tested with.

No good. Still nothing. When I run the program i'm getting the RX and TX lights to come up and flash like there is data being sent and received but the arduino just isn't responding.

Which example VI are you using to blink a LED?  Or are you using a VI you created?
