FTChipID.dll : Error Related

[systems_eng]

I'm working with a LabVIEW project that communicates through a USB connection with some peripherial devices.  There is a Call_Library_Function_Node.vi that is called in the project.  However, the library that it calls is non-existant.

FTChipID.dll is the shared library that it calls.  I managed to find a downloadable file here.

But so far, LabVIEW doesn't recognize the file.  Here are a listing of errors that I receive when I try to load the .dll...

  - The oridnal 71 could not be located in the dynamic link library FTD2XX.dll

  - The file 'FTChipID.dll' is not a valid LabVIEW file.

I also downloaded FTD2XX.dll from the site, so I'm not exaclty sure what my problem is.  Do these files need to be in a specific directory?  Do I  have to install these drivers in order to get LabVIEW to recognize both of the files?  If anyone has suggestions, shoot.

Hi Systems....,

I have worked with FTI DLLs and they rock........To your question ,you have to install the Driver .as far as I know in the FTDI web site there is how to go about this.

About the errors that you have .Try to copy the DLL in the same Directory where you have your VIs.

I hope I have being able to help?? Kindly post  again so I can follow up .
Good luck.

Thanks for the response.  I actually figured my problem out.  The site FTDI site didn't exaclty have what I was looking for.  Although my project was looking for the FTDXX.dll, I needed an executable that would install the driver(s).  I tried downloading the FTChipID.dll and the FTDXX.dll and storing them in a variety of directories (ie. - windows/systems32 as well as the root folder of my projects), but niether of the two worked.

Here is the .exe that I used to install the drivers, just in case someone needs it for a future reference.

Since I ran the zip file "FTD2XXUN.zip 200 KB" my application does not work anymore: it asks for the file "FTD2XX.dll" and afirms that it is not installed on my computer, although it is !

Has anyone an idea on how can I fix this bug ?

Thanks,

Hi tectec,

Which FTDI product are you using.  This post is from 2006, so it is possible that the driver you downloaded is not supported by your device or OS.  Here is a list of products from FTDI which will link you to their respective drivers:

Hello Brian,

Thank you for your reply and for the link.

In fact I knew that link already, but I was not able to use the information contained there to solve my problem.

So at the end to solve my problem, I set my computer back to a recovery point which I set one day before I started to get the problems by unziping and installing that executable.

By the way I am using LV2010 under Windows 7.

Hi tectec,

Just to clarify, have you been able to install the proper executable to get your device to work?  Your original post seems to hint at the fact that your application worked before installing the executable.  Please let me know if you are still experiencing problems and which particular device you are trying to install drivers for.

Thanks,

Brian
