ardunio 鼠标控制

Question

我想使用ardunio lenonardo来模拟鼠标运动。
我使用旋转编码器来控制鼠标运动，转速越大，鼠标运动越快，mouse.move 只在y轴上运动。低速转动时鼠标反应还好，但当旋转编码器高速转动时鼠标并未灵敏反应。

ardunio代码如下
#include <Mouse.h>
#define encoderPin  A0
#define maxEncoderValue  1023

volatile unsigned int currentEncoder0Pos = 0;
volatile unsigned int previouscurrentEncoder0Pos = 0;

long wheelValue = 0;

bool isWheelValuePositive = true;
unsigned long lastActivationTime = 0; // 上次激活的时间
const unsigned long activationDelay = 5000; // 延迟时间，单位为毫秒

void setup() {
  pinMode(encoderPin, INPUT);
  pinMode(11,INPUT);//left mouse
  Mouse.begin();
  Serial.begin (9600);
  pinMode(6, OUTPUT); // Direction
  pinMode(5, OUTPUT); // Step
  pinMode(7, OUTPUT);
  pinMode(4, INPUT); // FeedingTouch
  pinMode(3, INPUT); // Stop
  pinMode(8, INPUT);
  digitalWrite(7, LOW);
}

void loop() {

  updateMouseWheel();
  currentEncoder0Pos = analogRead(encoderPin);
  
}



// output mousewheel positive value when going in one direction
// and output a negative value when going in the opposite direction
void updateMouseWheel()
{
  
  
  // 检查编码器的位置是否发生了变化
  if(previouscurrentEncoder0Pos != currentEncoder0Pos)
  {
    // 如果当前的读数大于上一次的读数，那么认为是顺时针旋转
    if(currentEncoder0Pos > previouscurrentEncoder0Pos)
    {
      // 如果滚轮之前是在反方向滚动，那么将滚轮值重置为0
      if(!isWheelValuePositive)
      {
        wheelValue = 0;
        isWheelValuePositive = true;
      }
      // 使滚轮值递增
      wheelValue++; 
    }
    // 如果当前的读数小于上一次的读数，那么认为是逆时针旋转
    else if(currentEncoder0Pos < previouscurrentEncoder0Pos)
    {
      // 如果滚轮之前是在顺时针方向滚动，那么将滚轮值重置为0
      if(isWheelValuePositive)
      {
        wheelValue = 0;
        isWheelValuePositive = false;
      }
      // 使滚轮值递减
      wheelValue--;
    }

    // 更新前一次的编码器位置为当前位置
    previouscurrentEncoder0Pos = currentEncoder0Pos;

    // 在串口打印出滚轮值
    Serial.println (wheelValue);
    

    // 模拟鼠标在y轴上的移动
    Mouse.move(0,wheelValue,0);
  }
}

#include <Mouse.h>

#define encoderPinA A0
#define encoderPinB A1
#define encoderButtonPin 2
#define movementSpeed 5

int encoderPos = 0;
int lastEncoderPos = 0;

void setup() {
  pinMode(encoderPinA, INPUT_PULLUP);
  pinMode(encoderPinB, INPUT_PULLUP);
  pinMode(encoderButtonPin, INPUT_PULLUP);
  
  attachInterrupt(digitalPinToInterrupt(encoderPinA), updateEncoder, CHANGE);
  
  Mouse.begin();
}

void loop() {
  if (encoderPos != lastEncoderPos) {
    int movement = (encoderPos - lastEncoderPos) * movementSpeed;
    Mouse.move(0, movement);
    lastEncoderPos = encoderPos;
  }
  
  if (digitalRead(encoderButtonPin) == LOW) {
    Mouse.click(MOUSE_LEFT);
    delay(200); // 延时以避免连续点击
  }
}

void updateEncoder() {
  static int previousState = 0;
  int currentState = digitalRead(encoderPinA);

  if (currentState != previousState) {
    if (digitalRead(encoderPinB) != currentState) {
      encoderPos++;
    } else {
      encoderPos--;
    }
  }

  previousState = currentState;
}
