LED8位流水灯

本程序实现的功能是，把端口RC的8条引脚全部设置为输出模式，依次从引脚RC0

到RC7送出高电平，然后再依次从引脚RC7到RC0送出高电平，并且周而复始，从而

使得与该端口C相连的8只发光二极管LED循环依次点亮，其效果类似于一个简单的霹雳灯-The functionality of this program LED8 bit light water 8 port RC pin is set to output mode, turn sends a high level from pin RC0 to RC7 then in turn sends a high level from pin RC7 to RC0 , and again and again, making eight light-emitting diode (LED) connected with the port C cycle were lit, the effect is similar to a simple Thunderbolt lights
