这是一个针对AVR单片机的串口编程，里面有原理图，加上串口源码。针对型号为ATMEGA128的AVR单片机使用。其它的芯片，如果寄存器一样也可套用。

pic单片机c口的控制 单片机相应的I/O口设置为输出口，输出高电平时LED点亮，反之，LED不亮。利用软件延时的办法实现05S延时，实现LED流水灯的效果。-pic Singlechip c I control the corresponding single-chip I/O port set to output, the output high when the LED light, on the contrary, LED does not shine. Approach to the use of software latency delay 05S realize, realize LED lights flowing effect.
