linux下演示的一个小程序——跑马灯！运行后可以从IO口以此输出电平，让灯进行闪烁！-under demonstrated a small program -- 5,250! After running from the mouth IO this output level, lamps flicker!

通过网络编程实现LED灯奇数偶数灯闪烁显示，实现流水灯功能。-Through the network programming LED lights blinking display odd and even, to achieve water lights function.

51开发板中第2个程序点亮所有led，运行程序后会自动点亮所有小灯(The second program in the development board lights up all the leds, and the running program automatically lights up all the small lights)

51开发板中第3个程序循环流水灯，运行程序后会自动点亮所有小灯并闪烁(The 3rd program in the development board is circulating the running water lamp, which will automatically light all the small lights and blink when the program is running)
