Arduino USBHost - mouseReleased()用法及代码示例

void mouseReleased(){
//statements
}

#include <MouseController.h>

// Initialize USB Controller
USBHost usb;

// Attach mouse controller to USB
MouseController mouse(usb);

boolean left = false;
boolean middle = false;
boolean right = false;

void mousePressed() {
  if (mouse.getButton(LEFT_BUTTON))
    left = true;
  if (mouse.getButton(MIDDLE_BUTTON))
    middle = true;
  if (mouse.getButton(RIGHT_BUTTON))
    right = true;
}

// This function intercepts mouse button release
void mouseReleased() {
  Serial.print("Released: ");
  if (!mouse.getButton(LEFT_BUTTON) && left==true) {
    Serial.print("L");
    left = false;
  }
  if (!mouse.getButton(MIDDLE_BUTTON) && middle==true) {
    Serial.print("M");
    middle = false;
  }
  if (!mouse.getButton(RIGHT_BUTTON) && right==true) {
    Serial.print("R");
    right = false;
  }
  Serial.println();
}

void setup(){
  Serial.begin(9600);
}

void loop(){
  usb.Task();
}
