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.
