伟福LAB2000单片机仿真系统直流电机控制:利用实验仪上的D/A变换电路，输出-8V至+8V电压，控制直流电机。改变输出电.压值，改变电机转速，用8255 的PB.0 读回脉冲计数，计算电机转速。在电压允许范围内，直流电机的转速随着电压的升高而加快，若加上的电压为负电压，则电机会反向旋转。本实验仪的D/A变换可输出-8V到+8V的电压，将电压经驱动后加在直流电机上，使其运转。通过单片机输出数据到D/A变换电路，控制电压的高低和正负，观察电机的旋转情况。
在电机转盘上安装一个小磁芯，用霍尔元件感应电机转速，用单片机控制8255读回感应脉冲，从而测算出电机的转速。

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.

首先，分别对8255、8253进行初始化，设置8255为A口、C口输出，设置8253的计数器0为工作模式3；其次，设置IRQ7的中断矢量，使得有IRQ7中断时调用SERVER；再次，调用INIT对计数值初始化；最后，主程序循环等待中断，开始秒表的计时。 2、 INIT子程序-First, the 8255,8253 initialization, set for the 8255 A-C mouth output, set 8253 as the Counter mode 0 3; Second, set up the interruption vector there, make it there interruption call SERVER; Again, call curl_setopt early to count before; Finally, the cycle of waiting for the main program interruption began stopwatch time. 2, curl_setopt Subroutine
