AD7606调试过程与源码展开全文公司有一个项目用到了AD7606，控制器用的STM32，使用的模式是并行16位模式，程序刷好之后发现读取的AD数据乱码，结果发现是因为AD7606的接地不对，当然这个问题是我师傅找出来的，查找的过程如下：用示波器看了BUSY线,转换线等各种线的波形，目的是确定芯片是否正常工作。

师傅又测量了V1通道两端的波形，在没有给输入的情况下发现存在波形。

后面师傅又去看了下手册，发现V1通道需要接AGND，基准电压接地脚同样要接AGND，但是在电路中，V1与V8通道与基准电压接地脚的地线都分开了，通道接到了24V地，基准接到了3V3，所以导致读取的数据乱码。

原因就是地线分开了。
