仿真步骤如下： 1、把3个帖子的内容分别保存为51t9py.c,51t9py_indexa.h,5py_mb.h，放在同一目录下，将51t9py.c加入工程编译 2、由于Keil的模拟串口是单字节显示，汉字显示为乱码，所以要加挂RICHWIN或RichView这种会重新刷新显示的中文平台，或手工刷新屏幕，所以请先到 http://www.pchome.net/dl/chinese.htm 下载RichView，安装运行 3、在Keil环境下可以直接按“Ctrl＋F5”键仿真，按“F5”全速运行，切换到在串口依次输入: // 64*.6 426***.5 98*.7 936.3 586.1 4826*.1 9464*.7 64*.6试试:-) 4、按键对应(根据我自己的手机设置的,全部在PC的小键盘操作)： -simulation steps are as follows : 1 and 3 respectively, the content of messages posted on the preservation of 51t9py.c, 51t9py_indexa.h, 5py_mb.h, on the same directory, will join the project 51t9py.c compiler 2, Keil is the simulation of single-byte Serial show , the Chinese showed gibberish, so need to add or RichView RICHWIN this show will re-set the Chinese platform, or manual refresh screen, so please download RichView http://www.pchome.net/dl/chinese.htm to install three operations in Central Keil Habitat can be directly "Ctrl+ F5" key simulation, according to the "F5" running full-speed, switched to the ser
