项目二奥运五环彩

1、项目二奥运五环彩灯的设计与仿真学习要求：1、仿真软件KEIL C及PROTUES的应用2、I/O端口的应用、移位寄存器的应用3、C语言循环程序及自定义函数学习主要内容n端口P1口结构、特点、应用n串入并出移位寄存器结构、特点、应用n用PROTUES绘制电路图n用KEIL C编写调试程序n汇编及仿真任务一 花样一环彩灯的仿真nP1口结构和特点P1口结构和特点n可作为输入和输出端口使用n可驱动4个TTL门电路n内部有30K的上拉电阻，输出带锁存，输入不带锁存n做输入端口时，先写入1使场效应管截止，再读入信号电路原理图XTAL218XTAL119ALE30EA31PSEN29RST9P0.0/AD0
