ADIS16477的SPI通信问题

MyLouise
on Apr 2, 2018

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。之后用示波器去查看ADIS16477的波形，并对照datasheet中的表中参数，发现所有条件均符合标准。连线时按照SPI的基本接法连线的，实在是找不出来问题，有没有哪位大佬能给出个主意。
