Description: 目前普遍采用的MCS51 和PIC 系列单片机通常只有一个(或没有)UART 异步串行通信接口,在应用系统中若需要多个串行接口(例如在多机通信系 统中,主机既要和从机通信又要和终端通信)的情况下,通常的方法是扩展 一片8251 或 8250 通用同步/异步接收发送芯片(USART),需额外占用单 片机I/O 资源。本文介绍一种用单片机普通I/O 口实现串行通信的方法,可 在单片机的最小应用系统中实现与两个以上串行接口设备的多机通信

[Other单片机课程设计-数字音乐盒

Description: 课程设计题目:数字音乐盒 课程设计要求:1.利用I/O口产生一定频率的方波,驱动蜂鸣器,发出不同的音调,从而演奏乐曲(最少三首乐曲,每首不少于30秒) 2.采用LCD显示信息 3.开机时有英文欢迎提示字符,播放时显示歌曲序号(或名称) 4.可通过功能键选择乐曲,暂停,播放。 5.选作内容:显示乐曲播放时间或剩余时间 硬件电路:本设计中用到了89C51单片机,4*4键盘,蜂鸣器,16*2 LCD,七段 显示数码管LED。 原理说明:当键盘有键按下时,判断键值,启动计数器T0,产生一定频率的脉冲,驱动蜂鸣器,放出乐曲。同时启动定时器T1,显示乐曲播放的时间,并驱动LCD,显示歌曲号及播放时间。也可在LED显示歌曲号。
