I need to get the original digital data converted by AD1938. Any one knows how to get it? Thank you very much.
The USBi has no access to the data. It is only connected to the I2C port of the 1442.
The evaluation board has an SPDIF interface for transmitting and receiving digital audio. There are devices on the general market that allow you to connect a computer to an SPDIF interface. You may have a sound card with that functionality. So this is the simplest way to capture the audio into the computer.
This post shows how to connect and use the SPDIF interface of the eval board. You have to read into this post because the answer is not at the start of the post.
Another place to look for information is our Wiki page.
Here is a link to a file on the Wiki page that is doing something similar to what you need.
Here is the link to the Wiki page where this last file was obtained.
Tutorials [Analog Devices Wiki]
This is all explained in the Quickstart guide and more detailed in the User guide. Your evaluation board should have come with those documents? Do you have them? The user guide is available Here: http://www.analog.com/media/en/technical-documentation/user-guides/UG-032.pdf
The Quickstart guide does not seem to be on our new web site. If you need it le me know and I will send over a PDF.
Yes, the Quickstart is exactly with my evaluation board. But it just explains how to install sigmaStudio and setup USBi, also explains an example as "Your First SigmaStudio Project - EQ and Volume Control".
I need to store the digital data after ADC in a file, which will be a source file for my further use. Is there any way? Mybe I can use the USBi to read the digital data.
Thank you. I'll try it later.
