说明：  在Ubuntu环境下，建立arm-linux-gcc的交叉编译环境，开发的友善6410核心板上4个led灯的驱动程序，利用insmod安装后，会自动建立/dev/led节点，给节点写入1，则1#灯亮，写4，则4#灯亮，在写4，则4#灯灭。
(In the Ubuntu environment, the establishment of arm-linux-gcc cross-compiler environment, development-friendly core board 4 6410 driver led lights, use insmod installed, will automatically create a/dev/led node to node to write a , then the lights# 1, write 4, 4# lights, in writing 4, 4# lights off.)
