答案对人有帮助，有参考价值 0 找一个家里闲置的遥控器。上某宝买一块“红外解码模块”。再买一个带线的“USB转TTL USB转串口下载线CH340G模块”。像我这样，把线接到一起。找个好看的塑料外壳。把这些都装里面，PC电脑遥控器的接收设备就做好了。把这个设备插上电脑，安装USB串口线的驱动，可以看到我的电脑识别出串口 com 6 。打开串口测试软件，像我这样设置。按下遥控器上的按钮，就可以直接看到接收到的遥控器数据了。然后用你熟悉的PC桌面版本的编程语言，写一个串口接收程序来控制电脑就可以了。我用的是Qt，串口接收到的数据，对应上你要模拟的遥控器上的按键就可以了。模拟键盘上键，模拟键盘下键，模拟音量大小按键。根据自己的遥控器按键编码，修改如下程序即可。 if(receive_data)//向上Key_Up 00ff96 { //on_key_Up(); keybd_event(38,0,0,0); keybd_event(38,0,KEYEVENTF_KEYUP,0); } if(receive_data)//向下 00ff92 { keybd_event(40,0,0,0); keybd_event(40,0,KEYEVENTF_KEYUP,0); } if(receive_data)//向左 00ff97 { keybd_event(37,0,0,0); keybd_event(37,0,KEYEVENTF_KEYUP,0); } if(receive_data)//向右 00ff8c { keybd_event(39,0,0,0); keybd_event(39,0,KEYEVENTF_KEYUP,0); } if(receive_data)//ok { keybd_event(32,0,0,0);//空格 keybd_event(32,0,KEYEVENTF_KEYUP,0); } if(receive_data)//全屏 ctrl+回车 { keybd_event(17,0,0,0); keybd_event(13,0,0,0);//回车 keybd_event(13,0,KEYEVENTF_KEYUP,0); keybd_event(17,0,KEYEVENTF_KEYUP,0); } if(receive_data)//开始 { keybd_event(13,0,0,0); keybd_event(13,0,KEYEVENTF_KEYUP,0); } if(receive_data)//ESC { keybd_event(27,0,0,0); keybd_event(27,0,KEYEVENTF_KEYUP,0); } if(receive_data)//关机 { system("shutdown -s -t 00"); } if(receive_data)//win + D { keybd_event(91,0,0,0); keybd_event(68,0,0,0); keybd_event(68,0,KEYEVENTF_KEYUP,0); keybd_event(91,0,KEYEVENTF_KEYUP,0); } if(receive_data)//菜单 { keybd_event(164,0,0,0); keybd_event(164,0,KEYEVENTF_KEYUP,0); } if(receive_data)//鼠标左键 { mouse_event (MOUSEEVENTF_LEFTDOWN \| MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 ); } if(receive_data)//鼠标右键 { mouse_event (MOUSEEVENTF_RIGHTDOWN \| MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0 ); } if(receive_data)//w { keybd_event(87,0,0,0); keybd_event(87,0,KEYEVENTF_KEYUP,0); } if(receive_data)//e { keybd_event(69,0,0,0); keybd_event(69,0,KEYEVENTF_KEYUP,0); } if(receive_data)//q { keybd_event(81,0,0,0); keybd_event(81,0,KEYEVENTF_KEYUP,0); } if(receive_data)//音量静音键 { keybd_event(173,0,0,0); keybd_event(173,0,KEYEVENTF_KEYUP,0); } if(receive_data)//音量增加键 { keybd_event(175,0,0,0); keybd_event(175,0,KEYEVENTF_KEYUP,0); } if(receive_data)//音量降低键 { keybd_event(174,0,0,0); keybd_event(174,0,KEYEVENTF_KEYUP,0); } if(receive_data)//停止媒体键 { keybd_event(178,0,0,0); keybd_event(178,0,KEYEVENTF_KEYUP,0); } if(receive_data)//媒体暂停键 { keybd_event(179,0,0,0); keybd_event(179,0,KEYEVENTF_KEYUP,0); } if(receive_data)//媒体上一曲键 { keybd_event(177,0,0,0); keybd_event(177,0,KEYEVENTF_KEYUP,0); } if(receive_data)//媒体下一曲键 { keybd_event(176,0,0,0); keybd_event(176,0,KEYEVENTF_KEYUP,0); } if(receive_data)//recall 退格按键 { keybd_event(8,0,0,0); keybd_event(8,0,KEYEVENTF_KEYUP,0); } if(receive_data)//Tab { keybd_event(9,0,0,0); keybd_event(9,0,KEYEVENTF_KEYUP,0); } if(receive_data)//窗口切换 alt+tab { keybd_event(18,0,0,0); keybd_event(9,0,0,0); keybd_event(9,0,KEYEVENTF_KEYUP,0); keybd_event(18,0,KEYEVENTF_KEYUP,0); } if(receive_data)//alt+F4 { keybd_event(18,0,0,0); keybd_event(115,0,0,0); keybd_event(115,0,KEYEVENTF_KEYUP,0); keybd_event(18,0,KEYEVENTF_KEYUP,0); } if(receive_data)//声道切换 alt+a { keybd_event(18,0,0,0); keybd_event(65,0,0,0); keybd_event(65,0,KEYEVENTF_KEYUP,0); keybd_event(18,0,KEYEVENTF_KEYUP,0); } if(receive_data)//字幕切换 alt+L { keybd_event(18,0,0,0); keybd_event(76,0,0,0); keybd_event(76,0,KEYEVENTF_KEYUP,0); keybd_event(18,0,KEYEVENTF_KEYUP,0); }
