ds18b20的驱动程序，汇编语言编的，由两位数码管显示，程序已经在AT89C51上调通了，附带proteus仿真文件。-DS18B20 driver assembly language made by the two digital display, the program has had a rise in the AT89C51, incidental Proteus simulation file.

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
