Hello,

I have a question how to change USBi EVAL-ADUSB2EBZ data rate.

When SPI communication is made to the DSP with EVAL-ADUSB2EBZ,

it seems the speed is about 300 kbps.

Can I change the transmission data rate?

Thanks and Regards,

T.Tanaka

Hello T. Tanaka-san,

Unfortunately you cannot change the rate.

Hi Dave,

Thanks for your reply.

If high speed data communication with PC is required, do you recommend a general purpose USB-SPI bridge?

Thanks and Regards,

Hello T. Tanaka-san,

The speed issue is with the USBi interface and SigmaStudio expects to communicate with a USBi. So I think even SigmaStudio will keep the speed lower but I would have to research that.

Now, if someone has written their own user interface program to control the SigmaDSP directly, then the answer is yes, they could use any USB-SPI bridge and operate it much faster. The SigmaDSP is capable of much faster rates as you know. So if another interface can operate faster via USB then it would be a solution.

So let me know if SigmaStudio will still be used?

Hi Dave,

As I know, my customer don't use SigmaStudio and use high-speed data transfer with another software.

Thanks and Regards,
