8451 I2C Loop Running Slowly When Reading Data [ Edited ]

[cuuddii]

Hello,

I'm a bit new to LabVIEW and I'm having some trouble loading a particular VI. I was looking through the forums and I found some old posts from 2012, here the link:

You should use Producer>Consumer to achive faster aquire and queue saving to file

I tried to download the VI he/she attached but I when it's downloading I window pops up saying "Find the Control named ni845xControl.ctl", when I ignore it a few other windows pop up saying "Find the VI named NI-845x Close Device Reference.VI", "Find the VI named NI-845x I2C Write.VI", etc. Afterwards it says that I don't have NI845x.rc, but I recently downloaded that file and copied it into the objmgr folder, but I am still getting the errors.

I downloaded NI845x.rc from this site:

Does anyone know what I need to do to run the VI?

You need the actual driver - http://www.ni.com/download/ni-845x-14.0/4892/en/

Unless you have the hardware, not much point in trying the example, though.

Yeah, I just realized that. Not sure why I didn't think of that before. I really appreciate you taking the time to reply though, thanks and have an excellent day.
