use another firmware

[ziedhosni]

Hello,

I would like to use another firmware that I have already uploaded to control a stepper motor ( this facilitates the control through sending just a string and the motor executes). I run this with arduino software and it was working fine.

So my question is:

Is it ok to upload another firmware (not the HIFA.ino) find it attached?

Could you check why the VI I created is not working to control the motor. attached here also.

Thank for your help.

It is not possible to use two different firmwares on any Arduino at the same time.  You either need to write your own firmware such that it can communicate with LabVIEW (your custom functions) or you would need to modify an existing LabVIEW interface to run your stepper motor.

Yes you can use other firmware with Labview.

Please save a copy of your VI for Labview 2010.  Most people don't have access to Labview 2013.

Saved for LabVIEW 2009.

I suspect it is not working because the delay in the error signal is to short.  The Arduino Uno resets when Labview starts communicating with an Arduino Uno. During the reset period the Arduino Uno ignores all data sent to it.  Try a 2 second delay.   Typically it takes about 1.5 seconds for an Arduino Uno to reset.

Thank you guys for your help. Actually my problem was solved when I installed the NI visa 5.1.2
