ADS1194使用中碰到的奇特问题

Other Parts Discussed in Thread: ADS1194

采用ADS1194,MCU  STM32L4系列. 

问题描述如下: 

1. 标识芯片的第一个只读寄存器读取数据数据错误

2. 读取的数据每一个通道多了一个字节,把多出的字节去掉后位正确的数据,以方波实验: 

   DATA_RDY , 读取19个byte数据,得到的数据如下:

  C0 00 F3 00 56 5F 00 44 69 00 4C 33 00 4B 6C 00 00 00 00

  C0 00 F3 00 56 58 00 44 73 00 4C 13 00 4B 67 00 00 00 00

  按照3位读取,去除橙色标识的字节,显示为方波
