     I want to use the AD7768 evaluation board for collecting 8 input channel data simultaneously. The interface mentioned for this board is SDP-H1 as given in the user-guide. I have few questions regarding this.
    

    1. What is the time resolution of this DSP. Like what is the maximum delay in time for collecting data in several ( here 8 different) channels ? 
    

    2. For the SDP board what is its storage capacity. If we first want to save the data to the SDP board first and then send to the PC, how much data can we store at max? 
    

    3. Is there any demo code available for the interfacing and entire programming for the DSP-System Demonstration Platform (SDP) -PC connection? Also it will be extremely helpful if some demo videos can be provided where it shows the connection and working of these system mentioned. 
    

    Thank you in advance!

      Hi.
      

      You may use SDP-H1 as interface between PC and AD7768 eval board if you will also use ADI software to control the boards. Unfortunately, the source codes of these boards are neither accessible nor customizable.
      

      For more information on SDP-H1, visit this link or go to www.analog.com/sdp . There is also a video on SDP in this page.
      

      It seems that you want to develop an interface for your specific application so we recommend the following open source code oriented platforms:
      

      1. Develop your own code for ADSP-BF527 and use its SPORT peripheral to talk to AD7768.
      

      2. Choose or design your own microcontroller board as suggested in this post.
      

      3. Use the open source reference design provided by ADI with ZedBoard. Here are the HDL and the companion bare metal software.
      

      Thanks,
      Shine
