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…
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。
ad7928 采样的时候是如何处理机制的
AD7928Data2.WRITE_SEQ = 0X11;
AD7928Data2.DONT_TCARE_9_ADD2 = 0X01;
AD7928Data2.ADD1_ADD0 = 0X00;
AD7928Data2.PM1_PM0 = 0X11;
AD7928Data2.SHADOW_DONT_TCARE_2 = 0X10;
AD7928Data2.RANGE_CONDING = 0X11;

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??
Can I get a schematic for the AD7928 eval board? I don't see it on the product page. Thanks!
Steve
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…
1. AD7928模拟输入前端的驱动电路是怎么设计的？可以看一下原理图截图吗？
2. AD7928通道切换后，经过多长时间的采集时间，再开始当前通道的转换的？
We are planning prototype board with AD chips. Particularly rms detector ad8361 , phase gain detector ad8302 and ADC ad7928. So my question is regarding connecting ad8361 and ad8302 outputs to ad7928 channel inputs without AMP. Will I face stability problems…
