你好，最近在弄这个adis16227的 震动传感器，
发现读取的数据与预想的不一致，有点疑惑，找不到adi的技术支持。
配置 REC_CTRL = 0x1112
也就是 manual_time 模式，0-5g 量程 ，100.189K的采样率
每次 置位GLOB_CMD 的 record start/stop 位来读取 x buff里的数据，
下表是x 轴正反向 大致垂直地面的采集数据， 前面是乘以5g 量程的lsb 0.1526 的数据， 后面是x_buff 寄存器里的数据，
很奇怪，这时候 为什么得不到1g 的数据， 居然还有负数， 我是x正向朝下的啊？
回复，谢谢 @guozhen2012@163.com
