Format is C/C++ simply DOS program thats can format floppy disk inserted to drive. It is the same as MS Format commad. This program demonstrate how to solve this problem. Program also demonstrate how to use Disk library. Program was written in old Bo

C编译器，可以运行在dos上。也可以运行在控制台环境中-MS C Compiler，which can run under dos.

中断程序的编写：在单片机系统的p1口上接有8个LED，LED的阳极接+5V，阴极接P1口的引脚。当P1口某一口线输出为0时，将LED点亮。在外部中断0输出引脚P3.2引脚上接上上拉电阻并接有一个按钮开关K1。用K1按钮来产生外部中断0的输入信号。定时器程序的编写：在AT89S51单片机的P1口上接有8个LED.下面采用定时器T0的方式一的定时中断方式，使P1口外接的8个LED每0.5秒闪亮一次。C51程序：在AT89S51的P1.0脚接有一只发光二极管，二极管的阴极接P1.0脚，阳极通过限流电阻
