Sony Lt26i 光感自动调节全开参数修改

首先打开systemetchw_config.sh ,找到

echo 0,0,0,0 > $dev/lcd-backlight/als/params #
[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 12900 > $dev/torch/max_current 

改为

echo 3,2,2,0 > $dev/lcd-backlight/als/params #
[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 12900 > $dev/torch/max_current
