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。 -err

用汇编语言实现任意两个十进制数的加法，附有详细解析。应用了跳转指令，模拟进位机制实现带进位的两数相加。

这是我们老师的PPT 事关于计算机接口的 是我们学校公认的高质量的课件 实为教学和学习的最好的参考-This our teacher"s PPT things on the computer interface is our school recognized the quality of the real courseware for teaching and learning of the best reference!

这是一个时钟程序，用VB编写的，本人是VB初学者，有问题的地方请大家多多原谅。也请各位高手们多多指教。-This is a clock program, prepared by the VB, I VB beginners, problem areas you will excuse me please. Hope you have a master exhibitions.

多功能数字钟：在手动校时功能时，选择是调整小时，还是分 若长时间按住该键，还可使秒信号清零，用于精确调时 -Multi-function digital clock: In the manual, when the school functions, the option is to adjust hours, or minutes, if a long time hold the key, so that second signal can be cleared for accurate time transfer
