新讯 刷 ImmortalWrt 后对 LED 调整优化

背景

默认状态 红色 led 闪烁，蓝色 led 常亮，不明所以。

优化后效果

  1. 开机启动状态下，红色 led 闪烁，蓝色 led 常亮。
  2. 正常状态下，红蓝 led 均为常亮。
  3. 长按三秒关机阶段，红色 led 快速闪烁，蓝色 led 熄灭。

具体操作

配置红色 led 监测 cpu 状态，绿色 led 关闭，蓝色 led 监测 无线网 状态。

uci set system.led_red=led
uci set system.led_red.name='red:power'
uci set system.led_red.sysfs='red:power'
uci set system.led_red.trigger='cpu'
uci set system.led_red.default='1'

uci set system.led_green=led
uci set system.led_green.name='green:wan'
uci set system.led_green.sysfs='green:wan'
uci set system.led_green.trigger='none'
uci set system.led_green.default='0'

uci set system.led_blue=led
uci set system.led_blue.name='blue:wlan'
uci set system.led_blue.sysfs='blue:wlan'
uci set system.led_blue.trigger='phy0radio'
uci set system.led_blue.default='1'

uci commit system
/etc/init.d/led restart

配置关机阶段，红色 led 快速闪烁，蓝色 led 熄灭。

vi /etc/rc.button/power 编辑电源键触发脚本，修改为如下内容并保存：

#!/bin/sh

[ "${ACTION}" = "released" ] || exit 0

if [ "$SEEN" -ge 3 ]
then
	echo 'none' > /sys/class/leds/blue:wlan/trigger && echo 'timer' > /sys/class/leds/red:power/trigger && echo 100 > /sys/class/leds/red:power/delay_on && echo 100 > /sys/class/leds/red:power/delay_off
	exec /sbin/poweroff
fi

return 0
