ADI 专家好，我这边在调试ADIS16477时遇到几个问题需要咨询一下：

        1、在ADIS477通过SPI通信与STM32F4进行通信的时候，在对ADIS16477加入了软件复位的控制寄存器，并按照手册加入了200ms的延时，但在测试数据时，静止状态下加速度会有很大的跳变在9.6-10之间。当我把这部分软件复位注释掉之后，在静态状态下可以稳定在9.81-9.83之间。请问这个是软件复位影响到了数据的传输吗？

        2、第二个问题就是在对ADIS16477进行动态测试的时候，让其与ADIS16375进行对比…

hi

   The nonlinearity of ADIS16477  is  0.2%(FS = 125°/sec), I have some questions about   error calculation.

  For example：

  X  axi  Angular ：100°/s ;

The nonlinearity error = 100°/s * 0.2% = 0.2°/s ;  Is that correct?

Hi all friends,

I'm ADI DFAE, recently, our customer was debugging ADIS16477-3 (customer has purchased a set of ADIS16477-3/PCBZ), customer's engineer found their SPI (MCU platform is Frescale K60) read ADIS16477-3 PROD_ID some times is 0x0000, but some…

I noticed that ADIS16477 has the following characteristics:
±0.1° axis-to-axis misalignment error;
Nonlinearity 0.2 ;
Factory calibrated sensitivity, bias, and axial alignment;

Q1:
I want to know if the ±0.1° axis-to-axis misalignment error is…

Hi,

When reading the DIAG_STAT register back from ADIS16477 over SPI I'm getting 0x0001 back as the response. According to the datasheet bit 0 is reserved so is this a valid response? I'm getting sensible responses for product ID and firmware version…

Hi.

I want to use ADIS16477 IC in my custom board which is hexagonal in shape. for best performance where should i place this component. is it must to place at exactly center of board?

问题描述：ADIS16477-3BMLZ的SPI通信问题，发送了正确的时序，却得到了不稳定的输出。

MASTER：MK64-FRDM

              时钟频率：937.5 kHZ(ADIS16477要求<2M burstread要求<1M)

              SPI配置:CPHA=1 CPOL=1      MSB FIRST   16BITMODE

              编程发出的时序如下图所示，而却读不出来正确的id号，并且收到的值会有变动，有时候会读出来0x405D(正确ID)而有时候又会读出别的数据。而发送2个周期的时序却怎么也读不出0x405D这个ID号…

We were not having access to Data Ready signal. Please clarify if it also essential in the internal clock free running mode. To avoid the data ready signal related issues, We carried out the following tests on Friday. Some of the observations were still…
