26、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

27、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 Er

28、ror(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

29、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文档编码:CR4H8I3H10H3 HH1K2D8I4X5 ZV7Q5B10E10U8文档编码:CR4H8I3H10H3 HH1K2D8I4X5 ZV7Q
