Question

我有以下情况。我尝试通过在Visual C ++ 2017中制作的arduino IDE和窗口应用程序来控制直流电机。我使用串行端口将Visual Studio中的数据处理成Arduino。这是我想要实现的目标：

我正在使用mouse_down事件（当我用鼠标点击按钮时，会发生一些事情），但是在按下时它只发送一个符号（U，D，R，L），导致DC电机只需移动一点点。如何让它运行并发送char直到按钮被释放？我应该使用某种循环吗？
我尝试使用键盘上的num键以相同的方式控制它。问题是，键不起作用，直到焦点放在它们上面（它们被鼠标按下/徘徊）。有没有办法摆脱焦点？

感谢您的帮助。

    data=Serial.read();
    analogWrite(motorPin1,motorSpeed);
    analogWrite(motorPin2,motorSpeed);

    xValues=analogRead(xPin);
    if((xValues>xIdleHigh) or (data=='R')) {
      motorSpeed=map(xValues,xIdleHigh,xRight,motorSpeedLow,motorSpeedHigh);
      analogWrite(motorPin1,motorSpeed);
      analogWrite(motorPin2,motorSpeedLow);
      Serial.print("TURNING RIGHT...");
      Serial.print("\n");
      delay(50);
    } 

    xValues=analogRead(xPin);
    if((xValues<xIdleLow) or (data=='L')) {
      motorSpeed=map(xValues,xIdleLow,xLeft,motorSpeedLow,motorSpeedHigh);
      analogWrite(motorPin1,motorSpeedLow);
      analogWrite(motorPin2,motorSpeed);
      Serial.print("TURNING LEFT...");
      Serial.print("\n");
      delay(50);
    }

    yValues=analogRead(yPin);
    if((yValues<=yUp) or (data=='U')) {
      if(pos<150) {
        pos+=1;
      }
      Serial.print("BARREL UP");
      Serial.print("\n");
      delay(50);
    } else if((yValues>=yDown) or (data=='D')) {
      if(pos>30) {
        pos-=1; 
      }
      Serial.print("BARREL DOWN");
      Serial.print("\n");
      delay(50);
    }
    servo.write(pos);
    delay(50);`
