单片机串行口通信

一．设计要求和原理说明

1.1 设计要求

触摸按键控制老鼠走迷宫应用实验基本要求：

A．MSP430F5529单片机上电后，LCD液晶显示“Slide fingers on touch pads”。 B．设计一个在LCD上显示的迷宫图。用一个符号表示老鼠。 C．触摸PAD电容按键，控制老鼠移动。带老鼠走出迷宫。发挥部分：

A．设计ＰＣ和４３０之间的串行口通信程序（参考ＵＳＢ通信实验）和通信协议，将对应的按键信息通过USB串行口输出到PC机。正文小四号宋体 1.2 原理说明二．系统硬件设计 2.1 „ 2.2 „ 三．流程图设计 3.1 „ 3.2 „ 四．程序设计 4.1 主程序
