[source in ebook] calc DL : 0: 本计算器是以 STC89C52RC 单片机最小系统为控制核心，另外增加了 1602 液晶屏，矩阵键盘，蜂鸣器， 8 位 led 灯等外围硬件电路。能实现加减乘除，小数，负数四则运算；有退格，复位功能；有累算功能；具有十进制转二进制，十进制转十六进制的功能。为增加计算器的实用性，将其的最大运算范围扩大到正负一亿，运算结果超出范围时，液晶屏显示 OVERFLOW! ，蜂鸣器长鸣提醒， 8 个 led 实现流水灯。二进制和十六进制的转化范围为 0~255 ，适用于单片机 8 个 IO 口的进制转化。其中，十进制转二进制时， 8 个 led 有相应指示，灯亮代表 1 ，灭代表 0 。同样，超出范围后出现如上提醒。另外，若出现错误的运算，如除数为零时，液晶屏显示 ERROR! ，蜂鸣器长鸣提醒。以上功能满足了题目的基本要求和发挥要求。- The calculator is based on STC89C52RC Smallest single-chip system for the control of the core, Also increased 1602 LCD screen, Matrix keyboard, buzzer, 8 Position led Lights and other peripheral hardware circuits. Math can be achieved, decimals, negative four operations There backspace, reset function has accrued functions has a decimal to binary, decimal to hexadecimal function. In order to increase Calculator practicality, Will expand to its maximum operational range of plus or minus one million, When the operation result is out of range, LCD display OVERFLOW! Buzzer sounding reminder, 8 A led Achieve water lights. Binary and hexadecimal conversion range 0 to 255 For SCM 8 A IO Band into the mouth. Among them, the decimal to binary, the 8 A led Corresponding means Shows, lights representatives 1 , Destroy representatives 0 . Similarly, as the out of range alert appears. Fu
