Android的SENSOR_DELAY_FASTEST不够快 [英] Android SENSOR_DELAY_FASTEST isn't fast enough

问题描述

我使用的传感器来平衡一个机器人，但 SENSOR_DELAY_FASTEST 只是提供了一个10Hz的采样率，这简直就是不够快。有抽样的方法更快？

有没有投票的方式感应器，而不是等待 SensorEvent ？

解决方案

  

有取样的方式更快？

SENSOR_DELAY_FASTEST 是一个0毫秒的延迟。你不能有负面的时间，至少就物理学家已经确定。因此，没有更快的延迟比 SENSOR_DELAY_FASTEST 。

使用 Traceview ，以确定您的时间被占用。这是可能的，它是你的code，它正在放缓的处理。

  

轮询的方式感应器，而不是等待SensorEvent？

没有，不好意思。

I'm using the sensors to balance a robot, but SENSOR_DELAY_FASTEST only provides a 10Hz sampling rate, which is simply not fast enough. Is there a way of sampling even faster?

Is there a way of polling the sensors rather than waiting for a SensorEvent ?

解决方案

Is there a way of sampling even faster?

SENSOR_DELAY_FASTEST is a 0ms delay. You cannot have negative time, at least as far as physicists have determined. Hence, there is no "faster" delay than SENSOR_DELAY_FASTEST.

Use Traceview to determine where your time is being taken up. It is possible that it is your code that is slowing down your processing.

a way of polling the sensors rather than waiting for a SensorEvent ?

No, sorry.
