单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)
