在实时检测和自动控制的单片机应用系统中，单片机往往是作为一个核心部件来使用，仅单片机方面知识是不够的，还应根据具体硬件结构，以及针对具体应用对象特点的软件结合，以作完善。
在生活和生产的各领域中，凡是有自动控制要求的地方都会有单片机的身影出现；从简单到复杂，从空中、地面到地下，凡是能想像到的地方几乎都有使用单片的需求。
模拟多通道压力系统是利用压力传感器采集当前压力并反映在显示器上，它可以分析压力过量程，并发出报警。
并采用电子秤原理可根据输入单价准确的计算出物体的金额。
本篇论文讨论了简单的倒计时器的设计与制作，对于倒计时器中的四位LED数码显示器来说，我为了简化线路、降低成本，采用以软件为主的接口方法，即不使用专门的硬件译码器，而采用软件程序进行译码。
1、加深对单片机的了解和运用，掌握单片机芯片80C5X系列的逻辑功能及使用方法，并且提高学生的设计能力，以及提高综合运用所学知识的实际运用能力。
1、培养我们查阅数据手册的能力，以及提高我们对查阅资料的运用和理解。
2、通过设计的过程了解单片机的开发过程，以及对软件硬件设备的选择和应用。
3、学习并加深对Keil的运用，4、熟悉模拟电路的应用与集成电路的引脚排列。

12864LCD显示倒计时程序
简介：第一行显示，距离系统爆炸时间第二行显示，还剩第三行显示，00时，00分，00秒第四行显示，周林按下旋钮开关，开始设定秒，秒编辑位闪动。
左右旋转设定数值，在按下开关，秒确定，设定分，分编辑位闪动左右调数值，再按下，分确定，小时位闪动。
左右转调小时，再按一下。
时间确定，开始倒计时。
到达定时时间后停止，并闪动。

简介：第一行显示，距离系统爆炸时间第二行显示，还剩第三行显示，00时，00分，00秒第四行显示，周林按下旋钮开关，开始设定秒，秒编辑位闪动。
左右旋转设定数值，在按下开关，秒确定，设定分，分编辑位闪动左右调数值，再按下，分确定，小时位闪动。
左右转调小时，再按一下。

简介：第一行显示，距离系统爆炸时间第二行显示，还剩第三行显示，00时，00分，00秒第四行显示，周林按下旋钮开关，开始设定秒，秒编辑位闪动。
左右旋转设定数值，在按下开关，秒确定，设定分，分编辑位闪动左右调数值，再按下，分确定，小时位闪动。
左右转调小时，再按一下。
时间确定，开始倒计时。
到达定时时间后停止，并闪动。
