Description: 单片机硬件系统设计原则一个单片机应用系统的硬件电路设计包含两部分内容:一是系统扩展,即单片机内部的功能单元,如ROM、RAM、I/O、定时器/计数器、中断系统等不能满足应用系统的要求时,必须在片外进行扩展,选择适当的芯片,设计相应的电路。二是系统的配置,即按照系统功能要求配置外围设备,如键盘、显示器、打印机、A/D、D/A转换器等,要设计合适的接口电路。 -MCU hardware design principles of a system based application system hardware circuit design includes two parts : First, the expansion of internal microcontroller that is the function modules, such as ROM, RAM, I / O, timer / counter, interrupt system can not meet the application requirements, must chip in for expansion, the selection of appropriate chips, The circuit design accordingly. Second, the system configuration, according to the functional requirements of system configuration peripheral equipment, such as keyboards, monitors, printers, A / D, D / A converters, it is necessary to design appropriate interface circuit.

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 " *" (
