此示例包括工作四功能的计算器

基于8051单片机的。该电路还演示了

行业标准的字母数字液晶显示模块，

与通用键盘模型。正如你所看到的，

后者可以模拟任何设计矩阵键盘

像你在乎吸引太多的现实主义。

同样有趣的是电路使用外部存储器的事实，

与8051和6264的RAM芯片之间的相互作用

模拟得出的。

两个8051和RAM芯片支持弹出窗口

可以选择从调试菜单一旦

调试会话正在进行。-This sample comprises a working four function calculator

based an 8051 microcontroller. The circuit also demonstrates

the industry standard alphanumeric LCD display model,

and the universal keypad model. As you can see,

the latter allows you to simulate any design of matrix keypad

with as much realism as you care to draw.



Also of interest is the fact the circuit uses external memory,

and the interaction between the 8051 and the 6264 RAM chip

is simulated as drawn.



Both the 8051 and the RAM chip support popup windows

which can be selected from the Debug menu once

a debugging session is under way.
