The discussion revolves around creating a LabVIEW program to control two AD9854 signal generators for an optical trapping setup. The user lacks experience in electrical engineering and LabVIEW, seeking existing virtual instruments (VIs) for the AD9854 control. They are using a PXI-7854R connected to a SCB-68A breakout box and suspect a timing issue in their project. Another participant suggests considering alternative National Instruments programming options and highlights concerns about sharing ZIP files. Ultimately, the user reports success in debugging the program with assistance, achieving the desired sine wave output.

I am trying to write a Labview program to control two AD9854's which will generate the signal for AODs in an optical trapping setup. Unfortunately I'm not an EE and I don't have much experience with Labview so I was wondering if someone already had the VI's to do this with Labview FPGA. We have a PXI-7854R installed in a PXIe-1062 Chassis. The 7854R is connected to a SCB-68A breakout box which is then connected to the AD9854 via ribbon cable. the AD9854 has a 14-pin DIP, 49.152 MHz fixed output, HCMOS logic, temperature compensated crystal oscillator (TCXO) installed (we are just using one board for now to test bench). I have been working off of the VI's supplied by the Comstock Lab which are available here: https://www.pa.msu.edu/people/comstock/software.html%C2%A0 but we only need the AD9854 control portion, not the whole Fleezers control. My project is attached if you want to take a look, I think its a timing issue. any help would be much appreciated. I can add more info if needed. Thanks.

Welcome to the PF. :smile:

Are you constrained to using LabView, or can you use another National Instruments programming paragigm? Do you have any other programming experience? How about others on your team? I'm currently using C# and NI Measurement Studio, which I'm much more comfortable with compared to the graphic icons of LabView.
 
Also, posting a ZIP file is problematic. ZIP files can carry viruses and present other problems. Can you post PDFs of what you are trying to show us? Thanks.
 
We got it working! Just needed some help from someone with some programming experience to do a bit of debugging. Making Beautiful sine waves now! Sorry about the .zip file.

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
