C8051F系列单片机交叉开关的配置实例-C8051F series microcontrollers crossbar switch configuration examples

1） 以单片机为核心部件组成一个音乐播放器。 2） 利用单片机的定时器产生乐谱的各种频率方波，信号经过放大后由喇叭发出声音。 3） 自行定义按键盘，每按一键，可选择一首歌曲进行演奏，某段音乐令单片机连续播放，演奏可通过按键来中断。 4） 在LCD上显示演奏歌曲的名称。 -1) the composition of the core components of SCM as a music player. 2) the use of MCU timer generated scores of the various frequency square wave signal through the amplified sound from the speakers. 3) self-defined keyboard, every click of a button, select a song to play, a certain period of continuous playback of music in SCM, playing by pressing a button to interrupt. 4) In the LCD displays the name of the song playing.

单片机音乐播放程序，附带三首已编音乐代码，音乐调声可调-Singlechip music player program, three have been incidental music code, music, acoustic tune adjustable

好多51的程序，还有串口发送短信的程序。-many procedures, sending messages Serial procedures.

本程序用于用单片机控制步进电机的转动。用单片机的某一个引脚实现控制，如果引脚电平为高则实现正转，反之为反转。所用单片机为日立系列h83664十六位单片机。本代码使用c语言实现，开发环境为日立系列单片机专用开发环境-This procedure for the use of single-chip stepper motor rotation control. With a pin MCU control, if the pin level is higher then realize to the contrary, for the inversion. Used in single-chip for Hitachi Series 16 Singlechip h83664. This code uses the c language, development environment for the Hitachi series of single-chip dedicated development environment
