1. 输入命令evtest 查看系统下所有按键、输入设备:

root@rk3568:~# evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
/dev/input/event0:      rk805 pwrkey
/dev/input/event1:      Lenovo Precision USB Mouse
/dev/input/event2:      HID 04f3:0103
/dev/input/event3:      HID 04f3:0103 Consumer Control
/dev/input/event4:      HID 04f3:0103 System Control
/dev/input/event5:      adc-keys
/dev/input/event6:      rk-headset
Select the device event number [0-6]: 

2. 按照上面提示选择测试按键,如RK3568 boot按键为 /dev/input/event5: adc-keys

则event number 为5:按下按键会打印value 1,松开按键则会打印value 0,如下图:

3. 自定义按键功能,配置文件为

/etc/triggerhappy/triggers.d/example.conf

如下为定义按键为reboot功能,亦为系统默认配置,用户可以根据需要自定义。
