设计要求：编写程序实现利用定时器演奏乐曲。本程序通过调用通用GENSOUND程序发出各种声音演奏乐曲。选择p播放音乐“太湖船”，选择q退出。...

编的不好，请多多指教，32位的十六进制转换十进制并显示。-series of the poor, exhibitions, the 32 hexadecimal and decimal conversion shows.

此程序为KEIL环境下开发的代码（开发环境备选里没有KEIL），功能在成功运行后可以播放“生日快乐”歌。所需要的开发硬件为AT89C51为主芯片的单片机。-This program is developed under the code in KEIL environment (development environment, where there is no alternative KEIL), features a successful running play " Happy Birthday" song. Required the development of hardware-based chip microcontroller AT89C51.

ST套件产生汽车防盗器报警声,本实例的目的是让大家学会用单片机产生声音的方法，学会计算程序所用时间 本实例的功能是能用16F84产生汽车防盗器的报警声，频率分两个0.1s第一个 0.1S频率从1.8K-3.5K匀速增加第二个0.1S频率从3.5K-1.8K匀速减少, 程序复位后,按S2喇叭叫两声,按S3喇叭叫15秒,中途可按S5停止. PIC单片机 烧写时应注意：配置位已经在程序中写明，加载HEX文件时会自动加载，烧写时不用再手动设置配置位。 实验时请注意套件跳线选择；-pic
