Arduino 阿杜伊诺操纵杆库，don'；t停止操纵杆

我正在用arduino pro micro在操纵杆上制作游戏板

从控制台输入上下命令，raspberry pi的gpio将输出这些命令，arduino将接收这些命令并将其输入游戏机

我使用ArduinoJoy SticklLibrary。

我想玩一场GBA游戏，但Dpad保持打印状态。 我怎么能只按一次向上键

此外，在下面的GIF中，上下键一次按下一次，但在中间按下右键或其他键不响应。

作为补充，我使用了一款名为retro freak的游戏机。

该代码使用以下代码

arduino_pro_micro_gamepad.ino

#include <Joystick.h>

#define OFFSET_BUTTON 2
#define OFFSET_DPAD 18

Joystick_ Joystick(JOYSTICK_DEFAULT_REPORT_ID,JOYSTICK_TYPE_GAMEPAD,
  4, 0,                  // Button Count, Hat Switch Count
  true, true, false,     // X and Y, but no Z Axis
  false, false, false,   // No Rx, Ry, or Rz
  false, false,          // No rudder or throttle
  false, false, false);  // No accelerator, brake, or steering

void setup() {
  // Initialize Button Pins
  pinMode(2, INPUT_PULLUP);  // Button 1
  pinMode(3, INPUT_PULLUP);  // Button 2
  pinMode(4, INPUT_PULLUP);  // Button 3
  pinMode(5, INPUT_PULLUP);  // Button 3
  
  pinMode(18, INPUT_PULLUP); // D-pad Up
  pinMode(19, INPUT_PULLUP); // D-pad Right
  pinMode(20, INPUT_PULLUP); // D-pad Down
  pinMode(21, INPUT_PULLUP); // D-pad Left

  Joystick.begin();
  Joystick.setXAxisRange(-1, 1);
  Joystick.setYAxisRange(-1, 1);
  Joystick.setYAxis(0);
  Joystick.setYAxis(0);
}

// Last state of the buttons
int lastDpadState[4] = {0,0,0,0};  // Up, Right, Down, Left
int lastButtonState[4] = {0,0,0,0};  // Button 1 - 4

void updateDpad() {
  for (int i = 0; i <= 3; i++) {
    int currentDpadState = digitalRead(i + OFFSET_DPAD);
    if (currentDpadState != lastDpadState[i]) {
      switch (i) {
        case 0: // UP
          if (currentDpadState == 1) {
            Joystick.setYAxis(-1);
          }
          break;
        case 1: // RIGHT
          if (currentDpadState == 1) {
            Joystick.setXAxis(1);
          }
          break;
        case 2: // DOWN
          if (currentDpadState == 1) {
            Joystick.setYAxis(1);
          }
          break;
        case 3: // LEFT
          if (currentDpadState == 1) {
            Joystick.setXAxis(-1);
          }
          break;
        }
      lastDpadState[i] = currentDpadState;
    }
  }
}

void updateButton() {
  for (int i = 0; i <= 3; i++) {
    int currentButtonState = !digitalRead(i + OFFSET_BUTTON);
    if (currentButtonState != lastButtonState[i]) {
      Joystick.setButton(i, currentButtonState);
      lastButtonState[i] = currentButtonState;
    }
  }
}

void loop() {
  updateDpad();
  updateButton();
  delay(5);
}

---

只需在setup（）中对代码进行一点修改

改为：

  Joystick.setXAxis(0);
  Joystick.setYAxis(0);

---

尝试在…之前重置为初始值。。。或者在行动之后

if (currentDpadState != lastDpadState[i]) {
   reset();
   switch (i) {
    ...
   }
}


void reset(){
Joystick.setXAxis(0);
Joystick.setYAxis(0);
}

我的问题是使用操纵杆而不是开关

我想要的实现是只输入一次箭头键，所以我使用了hatswitch
