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。-Write a program, the program is running to make PC-1 may play into the " piano." When pressing the number keys 1 to 8, followed by issue of 1,2,3,4,5,6,7, I eight tones. Press CTRL+ C has withdrawn from the " Piano" state.

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
