DDC264EVM: DDC264EVM read sampled data from multiple boards

Part Number: DDC264EVM
Other Parts Discussed in Thread: DDC264

Hello,

we are developing a software to read the sampled data from 7 DDC264EVM boards (connected via USB to a PC) using the USB_IO_for_VB6.dll

We are able to read the the FPGA registers of the 7 boards using the WriteFPGARegsC function passing to it the USB device we want to read from.

And we are able to read the sampled data using the function FastAllDataCap.

The problem is that is such function doesn't exist a parameter to pass to select the USB port to read from (in order to select the board) and we are able to read only the data of just one of the 7 boards.

Please could you suggest us how we can select the board to read from with the FastAllDataCap function?

By the way, also uising tyor software I can't select the board to read from.

Thanks,

Rosario

Hi Rosario,

Sorry but the person that developed the DLL left the team long ago and we can't support it beyond what is documented out there. That is what we say that the DLL is delivered "as is". Maybe there is something at a higher level that you can do (some kind of USB bridge) but no idea... Other than that, let's see if anyone else can add some info here (maybe to the second part of your email) but otherwise, I don't think we know how to do what you are requesting.

Sorry can't be of more help,

Eduardo

Hi Rosario,

Regarding your question on the FastAllDataCap function, your inference is correct.

It has not been designed to take the USB dev port reference as an input parameter.

Hi Eduardo,

thanks for your reply.

Please is it possible to have the USB_IO_for_VB6.dll source code along with your DDC264 demo software code so we can try do modify the dll to add the USB port parameter in the FastAllDataCap function?

If we'll succed, we can make the updated dll available for the community.

Thanks,

Rosario

Hi Rosario,

Sorry for late answer but I was hoping someone else would comment. I am not familiar with the details of the code (I don't even have it myself...). Let me ping some other folks...

Regards,

Eduardo
