感觉滤波后数据还是不太稳定，进行重复测量极差在0.2%左右，这正常吗？还是我配置的问题？
gaoyang9992006：
你这个超声波传感器是测距吗？ps单位的话，这应该很小的时间了，你测的这个最大值都不超过0.2ns,是不是距离太短了？没用过这个东西，不是太了解，根据常识，一般超声波都是测距或者B超这种，如果是这种应用那么人体传播速度为1450m/s，如果精确到0.1mm,那么传输时间为69K ps,相对你测的这个时间，貌似简直可以忽略。所以不太懂你这个是测的什么

我在做超声波水表测流速，数据是静态点的，感觉数据波动比较大
user5953009：
楼主能不能分享一下代码啊（ 老师让学这个但是看手册看了半天也没有搞明白寄存器的时序啥的（cry））
