RST为高电平，之后随着时间推移电源负极通过电阻对电容放电，放完电时RST为低电平。正常工作为低电平，高电平复位。2.显示模块：分析发光二极管显示电路：图 4 发光二极管显示电路分析:它是半导体二极管的一种,可以把电能转化成光能,常简写为文档编码:CR4H8I3H10H3 HH1K2D8I4X5 ZV7Q5B10E10U8文档编码:CR4H8I3H10H3 HH1K2D8I4X5

结组成,也具有单向导电性。当给发光二极管加上正向电压后,产生自发辐射的荧光。图中一共有五个发光二极管其中一个为电源指示灯,当学习板通电时会发光以指示状态。其余四个为功能状态指示灯,实际作用与学习板有关分析数码管显示电路图 5 数码管显示电路分析:数码管按段数分为七段数码管和八段数码管,图中所用为八段数码管(比七段管多了一个小数点显示位),按发光二极管单元连接方式分为共阳极数码管和共阴极数码管。共阳数码管是指将所有发光二极管的阳极接到一起形成公共阳极(COM)的数码管.共阴数码管是指将所有发光二极管的阴极接到一起形成公共阴极(COM)的数码管。数码管主要用来显示经电路板处理后的程序的运行结果。图中使用了八个八段数码管,可以显示八个0-15 的数字。使用数码管可以直观的得到程序运行所显示的结果.也可以显示预置在学习板上的程序,主要通过16 个开关来控制。四、硬件调试1、是否短路用万用表检查P2 两端是短路。电阻为0，则短路，电阻为一适值，电路正常。2、焊接顺序焊接的顺序很重要，按功能划分的器件进行焊接，顺序是功能部件的焊接-调试-另一功能部件的焊接，这样容易找到问题的所在。3、器件功能1）检查原理图连接是否正确2）检查原理图与PCB 图是否一致3）检查原理图与器件的DATASHEET 上引脚是否一致4）用万用表检查是否有虚焊，引脚短路现象5）查询器件的DATASHEET，分析一下时序是否一致，同时分析一下命令字是否正确6）通过示波器对芯片各个引脚进行检查，检查地址线是否有信号的7）飞线。用别的的口线进行控制，看看能不能对其进行正常操作，多试验，才能找到问题出现在什么地方。1、详细描述硬件安装过程中出现的故障现象，并作故障分析，及解决方法。六、软件调试文档编码:CR4H8I3H10H3

Vision环境下进行，在调试程序之前，需要对工程进行Debug 设置，选择软件仿真或硬件仿真。软件仿真使用计算机来模拟程序的运行，不需要建立硬件平台就可以快速得到某些运行结果；硬件仿真是最准确的仿真方法，必须建立硬件平台，通过PC 机硬件仿真器 用户目标系统进行系统调试。采用硬件仿真的方法，硬件平台即为带有图1 所示接口电路的单片机应用系统，设置硬件仿真环境的具体操作步骤如下：首先，点击所建工程：Project 菜单中的 Options for Target Targer 1，出现工程的配置窗口，点击 Debug 设置，选择KeilMcmitor-51 Driver.然后，设置仿真器参数。建议波特率设置范围30038 400。为避免程序中的中断和Keil硬件仿真环境中的中断互相冲突，不选择“Stop ProgramExecution with SerialInterrupt”。完成 51 单片机在Keil Vision环境中的硬件仿真环境设置后，可以进行程序的调试仿真。2、调试仿真1)导入测试代码：文件打开key and display.uvproj 2)重建全部工程：Projectrebuilt all target files 重建结果为:Build target Target 1 compiling main.c.linking.Program Size:data=36.0 xdata=0 code=554 key and display-0 Error(s),0 Warning(s).3)调试：调试 Start/Stop Debug session(Ctrl+F5)调试结果为：Connected to Monitor_51 V3.4 测试程序 key and display 软件调试故障分析：故障 1.程序不能拷贝进学习板。分析：学习板是否连接计算机且安装驱动，又或是板供电不足。解决方法：确认已经在电脑上安装好学习板的驱动程序，而且使用对应的拷贝软件；检查 power 灯，若不亮，是否焊接不好或者学习板供电不足。故障 2.程序运行结果不正常分析：程序本身有问题，也就是说是错误的程序解决方法：检查程序是否正确，可使用排除法，将程序写入另一块能正常工作的学习板调试。故障 3.软件调试过程中发生计算机死机分析：死机的原因与软件兼容性、硬件兼容性均有关。解决方法：检查是否调试软件与计算机操作系统发生兼容性问题或者学习板发生硬故障。七、心得这次课程设计让我受益匪浅,无论从知识上还是其他的各个方面。上课的时候的学习文档编码:CR4H8I3H10H3 HH1K2D8I4X5 ZV7Q5B10E10U8文档编码:CR4H8I3H10H3 HH1K2D8I4X5

ZV7Q5B10E10U8从来没有见过真正的单片机,只是从理论的角度去理解枯燥乏味。但在实习中见过甚至使用了单片机及其系统,能够理论联系实际的学习,开阔了眼界,提高了单片机知识的理解和水平。单片机是很重要的一门课程,老师和一些工作的朋友都曾说过,如果学好一门单片机,就凭这个技术这门手艺找一个好工作也不成问题。尽管我们在课堂学到的内容很有限,但在以后的学习中单片机还需要好好的深入研究和学习,学好了单片机也就多了一项生存的本钱。最后感谢老师对我们的精心指导和帮助,感谢同学们对我的帮助文档编码:CR4H8I3H10H3
