    BHI 160无法产生Host Interrupt信号

    Re: BHI 160无法产生Host Interrupt信号

    您好:

              非常感谢,按照您的建议修改代码后,对Host Interrupt的疑问已经解决。但是现在还有一个小问题,刚开启VS_TYPE_ACTIVITY_RECOGNITION功能时,会有2~4次的误触发,就是传感器处于静止状态也会检测到运动,读FIFO后在回调函数判断sensor_id是VS_TYPE_ACTIVITY_RECOGNITION,2~4次误触发后,运动检测功能才正常工作,后续不会有误触发,请问有什么方法可以解决误触发的问题吗?

    Hello zhouy,

    加载完固件之后会收到几次中断,这是activity的初始状态。你可以在软件上不处理刚加载完固件的那几次中断,但FIFO要读。

    您好:

            请问有什么方法可以改变虚拟传感器ACTIVITY_RECOGNITION的检测灵敏度吗,测试的时候发现有些不剧烈的运动不能被检测到。另外,虚拟传感器ACTIVITY_RECOGNITION的采样率好像不能通过sample_rate参数进行设置,这导致有些运动检测结果报告延迟时间较长。

    Hello zhouy,

    ACTIVITY_RECOGNITION是固件里面的算法对一类活动的识别,算法只输出结果,不支持参数配置。
