USB NI-VISA driver

[isaac_lescano]

Hi,
I am working in a project for building an electronic card based on an FPGA.
To send data out I will use the USB controller CY7C68001 in my PCB board connecto to the FPGA.

I was looking for a way to retrieve the data in a PC. So, I reviewed my Labview 8.2 software and I learned about NI-VISA USB.

I also read the following page:

http://digital.ni.com/public.nsf/websearch/E3A2C4FE42D7ED0D86256DB7005C65C9?opendocument&Submitted&&node=133020_US which shows a way to get raw data from almost any USB device.

From my best understanding, I think NI-VISA should work for my application.

However, I wanted to confirm if I can use NI-VISA USB to get raw data from the CY7C68001 directly? Did somebody have experience with similar application?

Thank you very much,

Isaac Lescano

Hey Issac,

 A tutorial that you should look into is the USB Instrument Control Tutorial, I have not specifically used the CY7C68001 but you should be able to see the raw data using this technique.

Hi Isaac,

i'm very curious about whether you've got the CY7C68001 to work. I'm working with a more or less similar USB controller which i can't get to work.

Hello,

I am in the process of building my FPGA based board with the CY7C68001. I expect to finish it by the end of May, then I will test it. By that time I will post here any results.

Thanks,

Isaac

Hello Thsc,

Finally, until few delays on building my FPGA board, I was able to test the CY7C68001  USB controller embedded in my FPGA board. The news is that the USB NI-VISA driver works very well with the CY7C68001  USB controller.

I was able to program the descriptor variables (configuration data) of the CY7C68001 using the FPGA. Then I did a program in Labview that read that data on PC's USB port and writes all the data into a binary file. It works very well..!!!

Hey Isaac,

I was wondering if you still have the labview program for reading the data.

I have tot do a simular task that you describe here.

Kind regards,

Joris
