编写程序，程序运行时使PC机成为一架可弹奏的“钢琴”。当按下数字键1~8，依次发出1，2，3，4，5，6，7，I八个音调。按CTRL+C则退出“钢琴”状态。...

这是一个计算数字平台长度的程序，如： 运行时输入： 111122333，结果为: 4 　　　　　　　　 1111 注：本程序在dos中或windows98中运行。　-This a digital platform length calculation procedures, such as : Runtime input : 111122333. results : 4 1111 Note : this procedure dos or running Windows98.

汇编语言 封装的输入输出函数 可以直接调用-Assembly language package input and output functions can be directly invoked

这是一个数码管0-99计数器，请大家指点-This is a digital tube 0-99 counter, please instruct

用MASM写的显示系统时间的程序，内附源码和说明-written with Multiple Display System time-consuming procedures, and notes containing FOSS

This a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program. All written in masm assembler. There is also a small 252 byte driver that allows nonstandard floppy formats on dos systems below 7.0. Floppies can be formatted in any track and sector layout. 1.44M floppies can be formatted to 1.76 M. All source code,includes and libraries are included. Modify the bld.bat file to your own needs. There are many asm tricks in the source code. Have fun with this old code.-This is a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program.

本应用报告描述了如何使用定时器对RC5和SIRC电视红外遥控信号进行解码。本报告中描述的解码器是中断驱动的，使用定时器的特定功能来操作后台功能。只有一小部分msp430cpu？使用非实时资源。定时器模块的特定硬件位锁存功能用于红外数据信号的实时解码，独立于CPU，与CPU异步。CPU活动和功耗保持在绝对最低水平。定时器实现还允许其他任务同时发生（如果需要）。所提供的解决方案是专为MSP430x11x（1）和MSP430x12x衍生产品编写的，但可以适用于任何其他包含定时器的MSP430。基于MSP430的电视遥控器设计
