Description: 本设计以STC89C516RD+单片机为控制运算器，以8*6矩阵键盘控制，以12864ZB液晶显示，以9V电池供电。
对于此计算器我用了38个键的矩阵键盘，10个数字键，1个小数点键，1个正负键，4个常用运算键，1个等号键，1个清零键，1个第二功能键，4个三角函数运算键，4个常用公式键，还有8个其它功能键。此计算器与常用计算器无很大差别，其中四则运算、阶乘、百分比、平方、立方、组合、乘方、倒数都可以精确到十位 ，其它运算因为调用到C语言函数库，为浮点型，有效位只有7位。
-The design use STC89C516RD+ MCU to control the computing device, On 8*6 keyboard control, with 12864ZB matrix liquid crystal display (LCD),9v battery power.
For this calculator I used a matrix of 38 keys keyboard, 10 numeric keys, a decimal point key, a plus or minus keys, four common operation keys, an equal sign key, a Clear key, a The second function keys, four trigonometric functions keys, four commonly used formula keys, there are eight other function keys. This calculator and the calculator was no significant difference in common, including arithmetic, factorials, percentages, squares, cubes, mix, involution, the countdown can be accurate to 10, other operations because the call to C language function library for floating-point type, the effective bit only seven.

Description: 一、基础部分（70 ）
设计一个简易计算器，它具有下列运算功能：
1. 两个无符号的8位二进制数的相加；
2. 两个无符号的8位二进制数的相减；
3. 数值和运算符用4×4键盘输入，输入的值为十进制，其中A为“+”，B为“-”，C为“退格”E为“=”，
4. 数值用数码管以十进制形式显示，以加法为例，初始时显示全“0”，先输入被加数，输入时数字顺序是从左到右。例如，输入1、2、3应该在显示器上上显示“123”，在输入运算符，按下运算符键后，数码管显示全“0”，再输入加数，方法和前面一样，最后按下“=”，数码管显示运算结果
二、扩展部分（30 ）
在基础部分上增加乘法功能，实现两个无符号的4位二进制数的相乘，D为“*”（30 ）-First, the base portion (70 ) to design a simple calculator, it has the following expression: 1. Sum of two unsigned 8-bit binary number subtraction of two unsigned 8-bit binary number values and operators with 44 keyboard input, the input value is decimal, where A is the+ B for " -" C " backspace" E " =" Numerical digital tube In addition, for example, when the initial display of " 0" , the first input is addend input digital sequence is from left to right is displayed in decimal form. For example, enter 1, 2 and 3 on the display should be displayed on the " 123" digital display " 0" , the input operator, press the operator key, and then enter the addend, methods, and as before, and finally press under the " =" , digital display the result of the operation, expansion portion (30 ) increase in the base part multiplication function, the multiplication of two unsigned 4-bit binary number, D is the " *" ( Platform: |
