1 设计任务书

1.1 基本设计要求

（1）在综合单片机实验箱的硬件结构上编写软件完成设计。

的栈底。程序放置的地址须持续且靠前，不要在中间留下大批的空间地址，以使目标机可以应用较少的硬件资源。

（3）在液晶显示屏上显示测量的电阻电容，第一行显示measures第二行显示测的的值，如R=00.0KΩ或者C=00.00uF

（4）在电路中设定三个按键一个是换电阻的按键，其余分别为测电容和测电阻时的按键，当按下测电阻键时，显示相应的电阻值，当按下电容值时显示测得的电容值

（5）软件设计必须应用8052片内定时器，采用定时中断结构，可以采用软件中断的延时法。

1.2 选作项目

1、另设三个键，分别作液晶显示器的调校。

2、可以通过硬件电路，编写相应的软件程序，实现显示字幕的左移，右移等功能，本程序没有

3、同时也可以设置相应的量程来设计，本程序有相应的硬件电路，但软件读者可以自己编写

（2）程序的首地址应使目标机可以直接运行，即从0000H开端。在主程序的开端部分必须设置一个合适

2 设计阐明

12.1设计内容

用ZY15MCU12BD型综合单片机实验箱及串口电路设计实现显示时间并能够调校时间的时钟，还能够实现秒表的启动/暂停，复位功能。
