從基於軟鏈接的傳感器讀取

Question

如何從這些傳感器讀取數據？我剛剛找到他們的位置，但該文件夾似乎包含到其他位置的軟鏈接。我的目標是監測陀螺儀。

$ ls /sys/bus/iio/devices/iio:device* 
lrwxrwxrwx 1 root root 0 Jan 31 23:18 /sys/bus/iio/devices/iio:device0 -> ../../../devices/pci0000:00/0000:00:14.0/usb1/1-4/1-4:1.0/0003:0483:91D1.0018/HID-SENSOR-200073.1.auto/iio:device0

Answer 1

使用cat：

$ cat /sys/bus/iio/devices/devices/pci0000:00/0000:00:14.0/usb1/1-4/1-4:1.0/0003:0483:91D1.0018/HID-SENSOR-200073.1.auto/iio:device0 

Here is上IIO子系統一個漂亮的演示。
