Digispark kickstarter + JoyStick 模拟鼠标

IDE：Arduino 1.0.4

一、线路连接

S-Y ——> P5(A0)

S-X ——> P2(A1)

S-K ——> P0

VCC ——> VCC

GND ——> GND

二、Arduino代码

//from A0 start,the max is 1023 ,the max Vol is 5V
//A0 ==> P5 //from 470 begin ,less this can't working
//A1 ==> P2
//A2 ==> P4 but the value is smaller and can't read VCC ,maybe beacause it is used by USB conmunication

//#include "DigiKeyboard.h"
#include "DigiMouse.h"
const int buttonPin = 0;
const int ledPin =  1;
int buttonState = 1; 

void setup() {
}

void loop() {
  int x = analogRead(A1);
  int y = analogRead(A0);
  /*DigiKeyboard.sendKeyStroke(0);// prevent missing the first character after a delay:
  DigiKeyboard.print("(");
  DigiKeyboard.print(x);
  DigiKeyboard.print(",");
  DigiKeyboard.print(y);
  DigiKeyboard.println(")");
  DigiKeyboard.delay(1000);*/

  DigiMouse.moveY(y-537); //down 10
  DigiMouse.delay(100);
  DigiMouse.moveX(x-521); //right 20
  DigiMouse.delay(100);
  //DigiMouse.scroll(5);//pg up
  //DigiMouse.delay(500);
  buttonState = digitalRead(buttonPin);
  if (buttonState == LOW) {     //the JoyStick button down is low level
    digitalWrite(ledPin, HIGH);
    // three buttons are the three LSBs of an unsigned char
    DigiMouse.setButtons(1<<0); //1<<0 left click;1<<1 right click
    DigiMouse.delay(500);
    DigiMouse.setButtons(0); //unclick all
    //DigiMouse.delay(500);
  }
  else {
    digitalWrite(ledPin, LOW);
  }
}

说明：

1、DigiMouse.moveX(char deltaX)、DigiMouse.moveY(char deltaY)函数是相对当前位置进行移动；

2、DigiMouse.scroll(5);为向上翻页；

3、DigiMouse.setButtons(1<<0) 为鼠标左键单击，DigiMouse.setButtons(1<<1) 为鼠标右键单击，DigiMouse.setButtons(0)为清除单击事件;

4、鼠标单击函数执行后，设置合适的延时，可以实现双击。

ps：该Digispark kickstarter似乎存在一点问题，P5脚，即A0脚模拟量无法读取全部模拟量，只能从约470的AD值开始读（最大AD值为1023）。
