==连接并使用digispark==
===Bootloader:===

The bootloader is the code that is pre-programmed on your Digispark and allows it to act as a USB device so that it can be programmed by the Arduino IDE.

The Digispark runs the “micronucleus tiny85” bootloader version 1.02, an open source project: https://github.com/micronucleus/micronucleus originally written by Bluebie: https://github.com/Bluebie.

CAUTION We are not at this point supporting upgrading the firmware, so if you decide to, you do so entirely at your own risk.

===Software:===

The Digispark uses the Arduino IDE 1.6.5+ (Arduino 1.6.5r2 - NOT 1.6.6 or 1.6.7 strongly recommended)

====安装说明====
=====windows=====
* 首先下载arduino IDE ：http://www.arduino.cc/en/Main/Software (1.6.5以上版本)
* 双击运行arduino IDE， file -> preferences

* Tools -> Boad -> Boards Manager，type选择 "Contributed"，之后选择"Digistump AVR Boards" 安装包，点击"Install"按钮进行安装

* 等待下载安装完成后，会显示"Installed"；完成后，Tools -> Boards ->Digispark(Default - 16.5mhz)，新用户建议选择该项。

* 安装完成

=====Linux Install=====

* If you haven't before - Install the udev rules found here:[http://digistump.com/wiki/digispark/tutorials/linuxtroubleshooting Troubleshooting section]


====下载程序测试====

digispark 和其他arduino兼容产品不同，下面看看具体哪里不同？

* 板型选择：Tools -> Boards -> Digispark(Default - 16.5mhz) （Tools -> Programmer无需选择）
* 打开例程代码：File -> Examples -> Digispark_Examples -> Start <font color="red" size="+1">无需连接控制板</font>，代码如下：
<pre style="color:dimgray">
// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(0, OUTPUT); //LED on Model B
  pinMode(1, OUTPUT); //LED on Model A   
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(0, HIGH);   // turn the LED on (HIGH is the voltage level)
  digitalWrite(1, HIGH);
  delay(1000);               // wait for a second
  digitalWrite(0, LOW);    // turn the LED off by making the voltage LOW
  digitalWrite(1, LOW); 
  delay(1000);               // wait for a second
}
</pre>
* 点击"Upload"按钮，底部状态栏会提示要求连接digispark控制板，这时你需要将其插入
* 下载完成后，底部状态栏提示，如下图：

* 下载完成后，它将立即运行代码

PS：如果你拔掉digispark并重新供电，程序将延时5秒运行。这5秒延时是确定你是否想要运行此程序。
