本文介绍了一段Shell脚本，该脚本通过ADB命令调节设备上LED灯的亮度，实现从0到255级的渐变效果。脚本首先分别针对红、绿、蓝三种颜色的LED进行独立测试，随后同步改变三色LED的亮度。
#!/bin/sh
echo "begin to test led"
for color in blue green red; do
i=0
while [ "$i" -le 255 ]
do
echo $i
i=$((i + 1 ))
adb shell "echo $i > /sys/bus/i2c/devices/0-0045/leds/$color/brightness"
pwd
done
sleep 3
i=0
adb shell "echo $i > /sys/bus/i2c/devices/0-0045/leds/$color/brightness"
done
i=0
while [ "$i" -le 255 ]
do
echo $i
i=$((i + 1 ))
adb shell "echo $i > /sys/bus/i2c/devices/0-0045/leds/blue/brightness"
adb shell "echo $i > /sys/bus/i2c/devices/0-0045/leds/green/brightness"
adb shell "echo $i > /sys/bus/i2c/devices/0-0045/leds/red/brightness"
pwd
done
sleep 3
