微机技术实验时的控制8253，8255，0809，0832，进行的录音放音实验，用汇编语言实现，将源程序用MASM进行编译，然后用LINK进行连接，运行文件后，提示录音后按任意键开始录音，12秒后开始出现放音信息，按空格键可以重复放音，其他键放音一次后跳出程序。自己根据实验流程图编写，用于学习交流，有部分注解。-Computer Technology 8253,8255,0809,0832 control experiments, carried out by recording playback experiments, using assembly language to achieve, to the source code to compile with MASM, and then connect with LINK, run file, prompted by pressing any key after recording the beginning of recording, 12 seconds after playback of information began to emerge, according to the space bar can repeat playback, and other key after playing out a procedure. Experimental flow chart in accordance with the preparation of their own for the exchange of learning, some comments.
