2、从而发出不同的声音。(3) 通过8255的PA口，使G6区的17号键由低到高发出1-7的音阶。2设计要求 从课程设计的目的出发，通过设计工作的各个环节，达到以下要求：1） 掌握汇编语言程序设计的基本方法。2） 进一步理解各种接口电路的应用。例如8255并行接口。3） 掌握利用PC机扬声器发出不同频率声音的方法。4） 理解12864模块的应用。（此为创新添加部分）三、方案和工作原理说明1方案基于PC计算机的时钟晶振为1.1931816MHz，利用电脑里面的蜂鸣器发出声音。各音阶标称频率值：/*-*/音符:1234567 (低音)对应频率(Hz):1250135114281562166617851
