• RE: ad7928 connect  ADSP21369 with spi

    HI Deepa

     

    i read about the code,you given to me .now it miso pin also is high.

    and i can get the  value of  pRXSPI.  but the first value is right.then the value is 0xffff.

     

    can you help look the ad7928 ?  it seems the command write to the ad7928 which…

  • RE: ad7928读写控制问题

    您好!

    不能正常读到数据请先检查硬件设计,看硬件设计是否正确,硬件设计请参考附件内AD7928评估板原理图。确保硬件设计正确后,请检查焊接是否正常,通常虚焊或短路会导致芯片状态不正常。

    对于软件部分的检查,首先应保证初始化流程与数据手册中流程要求一致。在数字读写时,则应保证读写时序遵守数据手册中时序图。

    LBOUKHANA677,

    Similar to the AD7928 inquiry you'll want to look at the Materials Declaration Documentation attached to the Product Page.

    Apologies.

    The data is the same for both generics.  The information I provided you for the AD7357 is the same for AD7928

  • AD7928 need a big delay before the next channel to sampling to remove the charge of the capacitor from the earlier conversion??

  • RE: AD7928 Multi-channel problem

    Hi edge,

       The AD7928 conversion data needs 16 SCLK cycles to clock out the data. You re correct that the result is compose of 1 leading zero+ 3 ch identification bits + 12 conversion data.  The AD7928 is configured in the control register. This register…
