我们在做机器人调试时，只能通过串口发命令来控制，有时跟着出门了还得带着电脑，实在很不方便，今天来教大家如何使用PS2手柄来直接控制Arduino设备。 目录 隐藏 一、材料准备 二、连线方法 三、开发环境 四、调试代码 一、材料准备ps2手柄 *1 // 2.4G无线通信，遥控距离20米 连接线 *若干
注意电源接3.3V
添加PS2X库： # 下载 wget https://github.com/yanjingang/Arduino-PS2X/archive/refs/heads/master.zip # 复制到arduino应用插件目录 cp -r ~/Arduino-PS2X/PS2X_lib /Applications/Arduino.app/Contents/Java/hardware/arduino/avr/libraries/ 四、调试代码 #include "PS2X_lib.h" PS2X ps2x; // create PS2 Controller Class int error = 0; byte type = 0; byte vibrate = 0; void setup() { Serial.begin(57600); // 设置PS2控制引脚 error = ps2x.config_gamepad(13, 11, 10, 12, true,true); // setup pins and settings: GamePad(clock, command, attention, data, Pressures?, Rumble?) if (error == 0) { // 成功 Serial.println("Found Controller, configured successful"); Serial.println("Try out all the buttons, X will vibrate the controller, faster as you press harder;"); Serial.println("holding L1 or R1 will print out the analog stick values."); Serial.println("Go to [url]www.billporter.info[/url] for updates and to report bugs."); } else if (error == 1){ // 未找到控制器，请检查接线 Serial.println("No controller found, check wiring, see readme.txt to enable debug. visit [url]www.billporter.info[/url] for troubleshooting tips"); }else if (error == 2){ // 找到控制器但不接受命令 Serial.println("Controller found but not accepting commands. see readme.txt to enable debug. Visit [url]www.billporter.info[/url] for troubleshooting tips"); }else if (error == 3){ // 控制器拒绝进入压力模式，可能不支持 Serial.println("Controller refusing to enter Pressures mode, may not support it. "); } // Serial.print(ps2x.Analog(1), HEX); // 读取PS2设备类型 type = ps2x.readType(); switch (type) { case 0: Serial.println("Unknown Controller type"); break; case 1: Serial.println("DualShock Controller Found"); break; case 2: Serial.println("GuitarHero Controller Found"); break; } } void loop() { /* You must Read Gamepad to get new values Read GamePad and set vibration values ps2x.read_gamepad(small motor on/off, larger motor strenght from 0-255) if you don't enable the rumble, use ps2x.read_gamepad(); with no values you should call this at least once a second */ if (error == 1) // skip loop if no controller found return; // 读取手柄的控制信号 if (type == 2) { // Guitar Hero Controller ps2x.read_gamepad(); // read controller if (ps2x.ButtonPressed(GREEN_FRET)) Serial.println("Green Fret Pressed"); if (ps2x.ButtonPressed(RED_FRET)) Serial.println("Red Fret Pressed"); if (ps2x.ButtonPressed(YELLOW_FRET)) Serial.println("Yellow Fret Pressed"); if (ps2x.ButtonPressed(BLUE_FRET)) Serial.println("Blue Fret Pressed"); if (ps2x.ButtonPressed(ORANGE_FRET)) Serial.println("Orange Fret Pressed"); if (ps2x.ButtonPressed(STAR_POWER)) Serial.println("Star Power Command"); if (ps2x.Button(UP_STRUM)) // will be TRUE as long as button is pressed Serial.println("Up Strum"); if (ps2x.Button(DOWN_STRUM)) Serial.println("DOWN Strum"); if (ps2x.Button(PSB_START)) // will be TRUE as long as button is pressed Serial.println("Start is being held"); if (ps2x.Button(PSB_SELECT)) Serial.println("Select is being held"); if (ps2x.Button(ORANGE_FRET)) // print stick value IF TRUE { Serial.print("Wammy Bar Position:"); Serial.println(ps2x.Analog(WHAMMY_BAR), DEC); } }else { // DualShock Controller ps2x.read_gamepad(false, vibrate); // read controller and set large motor to spin at 'vibrate' speed if (ps2x.Button(PSB_START)) // will be TRUE as long as button is pressed Serial.println("Start is being held"); if (ps2x.Button(PSB_SELECT)) Serial.println("Select is being held"); if (ps2x.Button( PSB_PAD_UP)) { // will be TRUE as long as button is pressed Serial.print("Up held this hard: "); Serial.println(ps2x.Analog(PSAB_PAD_UP), DEC); } if (ps2x.Button(PSB_PAD_RIGHT)) { Serial.print("Right held this hard: "); Serial.println(ps2x.Analog(PSAB_PAD_RIGHT), DEC); } if (ps2x.Button(PSB_PAD_LEFT)) { Serial.print("LEFT held this hard: "); Serial.println(ps2x.Analog(PSAB_PAD_LEFT), DEC); } if (ps2x.Button(PSB_PAD_DOWN)) { Serial.print("DOWN held this hard: "); Serial.println(ps2x.Analog(PSAB_PAD_DOWN), DEC); } vibrate = ps2x.Analog(PSAB_BLUE); // this will set the large motor vibrate speed based on how hard you press the blue (X) button if (ps2x.NewButtonState()) // will be TRUE if any button changes state (on to off, or off to on) { if (ps2x.Button(PSB_L3)) Serial.println("L3 pressed"); if (ps2x.Button(PSB_R3)) Serial.println("R3 pressed"); if (ps2x.Button(PSB_L2)) Serial.println("L2 pressed"); if (ps2x.Button(PSB_R2)) Serial.println("R2 pressed"); if (ps2x.Button(PSB_GREEN)) Serial.println("Triangle pressed"); } if (ps2x.ButtonPressed( PSB_RED)) // will be TRUE if button was JUST pressed Serial.println("Circle just pressed"); if (ps2x.ButtonReleased( PSB_PINK)) // will be TRUE if button was JUST released Serial.println("Square just released"); if (ps2x.NewButtonState(PSB_BLUE)) // will be TRUE if button was JUST pressed OR released Serial.println("X just changed"); if (ps2x.Button(PSB_L1) || ps2x.Button(PSB_R1)) // print stick values if either is TRUE { Serial.print("Stick Values:"); Serial.print(ps2x.Analog(PSS_LY), DEC); // Left stick, Y axis. Other options: LX, RY, RX Serial.print(","); Serial.print(ps2x.Analog(PSS_LX), DEC); Serial.print(","); Serial.print(ps2x.Analog(PSS_RY), DEC); Serial.print(","); Serial.println(ps2x.Analog(PSS_RX), DEC); } } delay(50); }将示例代码上传到UNO板中，打开PS2无线手柄的开关（ON、START、MODE，确保两个灯都亮起），观察无线接收器的绿灯与手柄的上的灯都停止闪烁说明连接成功了。 打开串口监视器，可以看到连接成功，控制手柄查看信号接收是否正常（需要注意demo里两个摇柄的当前值是在按L1和R1时打印Stick Values输出的）。
按钮定义：
好了，单片机能准确的收到相应按钮信号之后，剩下的对应控制逻辑就不在此赘述了，自己实现即可。
