Calling dll file to control a third party board from PC Control.

[EmilyLiu]

Hi there,

I have this hawkeye stepper motor control board from PC control company. 

It comes with a software written by the company  which is in DLL format. I would like to call the DLL file in labview and be able to do further programming on it using labview platform to control the motor board. 

The reason that I need to call this DLL file is because labView does not recognise the control board when connected to it. 

 I would really be grateful if anyone who has purchased the same motor control board from PC control company before and successfully using labview to control it could share the code and driver with me. 

Many thanks.

Hello,

I'm not using that vendor products so I can't help you directly with your issue.

Nevertheless, you can find several documents on this site explaining how to use DLLs in LabVIEW: I point you to three of them, but yu can find more with apropriare searches.

Can LabVIEW C? - Example 3: Using the Right Tools with LabVIEW a whitepaper on using external DLs in LabVIEW

Calling External Code From LabVIEW link useful documents on how to call different external codes in LabVIEW

Using Existing C Code or a DLL in LabVIEW a tutorial which explainh how to use DLLs

I must also warn you that this is not the proper forum board where to post LabVIEW-related questions: this board is dedicated to LabWindows/CVI users, while there is a specific board for LabVIEW users where I suggest you to post further questions.
