Description: 本设计是16键盘简易计算器，利用一片AT89C51单片机，其并行口外接4×4矩阵式键盘，和八位七段共阴极LED数码管。
系统的功能是：（1）模拟的计算器能显示8位数字，开机运行时，只显示最低位为“0”，其余不显示；（2）4×4键盘分别表示：0到9，+，-，×，/，＝，CL；（3）第一次按下，显示“D1”,第二次按下，显示“D1D2”，第三次按下，显示“D1D2D3”…8个全显示完毕，再次按下按键时，给出 “嘀”的提示音；（4）可以对计算结果小于256的两个无符号数进行加、减、乘、除运算。-The design is simple calculator keyboard 16, using an AT89C51 single-chip, the external parallel port 4 × 4 matrix keyboard, and a total of eight team respectively cathode LED digital tube. The function of the system are: (1) analog calculator can display 8-digit run-time boot, only showed that the minimum bit to
