三星安卓手机的传感器采样频率

Question

什么是三星galaxy pop Android手机在SENSOR_DELAY_GAME中的传感器采样率.从哪里可以得到这些信息？我想使用加速计传感器.

提前致谢

Answer 1

根据ICS 源代码

case SENSOR_DELAY_FASTEST:
    delay = 0;
    break;
case SENSOR_DELAY_GAME:
    delay = 20000;
    break;
case SENSOR_DELAY_UI:
    delay = 66667;
    break;
case SENSOR_DELAY_NORMAL:
    delay = 200000;

那些是μs,所以SENSOR_DELAY_GAME将是20ms或50Hz

它仍然取决于你的硬件等.所以你可能想测量它来验证.
