一、安装：
对于 Genuino 101（在美国叫做 Arduino 101），目前最新的 Arduino IDE 还默认不会支持，需要手动安装驱动。
将 Genuino 101 插入电脑 USB ，等待基本驱动安装完毕后，打开 Arduino IDE。
然后打开“开发板管理器”，在“开发板管理器”中找到“Intel Curie Bords by Intel”，在右边点安装。
等4个步骤全部下载安装完毕后，将 Arduino IDE 关闭，拔出 Genuino 101。
重新打开 Arduino IDE ，插入 Genuino 101。在开发板选择中选中 Genuino 101。端口应该会自动识别，如果没有正确识别，再勾选正确的端口。
二、测试：
本段参考Arduino.cc官网指南：https://www.arduino.cc/en/Tutorial/Genuino101CurieIMUOrientationVisualiser
- 按Genuino 101入门中所述，设置Arduino软件（IDE）。
- 连接101和用户电脑。
- 启动Arduino软件（IDE），并从“工具 > 开发板” 菜单项中选择Arduino/Genuino 101。
- 由开发库管理器中安装Madgwick 库。可打开Arduino软件（IDE），选择”Sketch -> Include Library -> Manage Libraries”。然后搜索’Madgwick’ 并直接安装开发库。请参阅开发库安装指导 了解安装和导入开发库的更详细解释。
- 下载启动Processing软件 ，并使用如下所示处理代码创建一个文件。
- 修改串行端口，使用用户101开发板正在使用的端口号（参阅”处理代码”章节）。
- 上传CurieIMU 示例至用户101开发板，请确保开发板保持水平和静止以便进行精确校准。
- 几秒钟后，运行Processing代码，调整开发板方向，查看程序对开发板的可视化显示。
