NoticeRASPBERRY PI Arduino Shield ADD-ON/zh-cn
From ITEAD Wiki
概述
市场上有各种各样为Arduino定制的Shield和电子积木，而为树莓派定制的相对不多。这款RPI Arduino Shield Add-on 把树莓派的32PIN Connector 扩展为Arduino 引脚，可以方便连接各种Arduino Shields，同时引出2组Grove电子积木接口，可连接各种电子积木。
我们不仅仅只是提供一块可以方便的插在树莓派上面的板子，还为其配套提供了SDK，移植了Arduino上的驱动程序。安装完SDK后，就可以像在Arduino平台底下一样，非常轻松的驱动这块板子。
- 树莓派的32PIN 接口扩展为Arduino 引脚
- 2组Grove电子积木接口
- 2个电子积木接口
- 供电电压3V3、5V可调

Instruction
- Plug Rpi Arduino Shield Add-on into RPI V2, connect SHT10 to IIC interface through 4-pin wires. Power Raspberry Pi V2.
- Download the SDK from this link: https://github.com/iteadsw/SDK and then install it.
- Modify the file ReadSHT1xValues.ino
- modified codes as below:
- define dataPin 3
- define clockPin 5
- Enter into the directory libraries/itead_SHT1x/examples/ReadSHT1xValues, compile and run the file ReadSHT1xValues.ino
- Command as below to compile ReadSHT1xValues.ino
- $ iteadcompile ReadSHT1xValues ReadSHT1xValues.ino
- Command to run this program
- $ sudo ./ ReadSHT1xValues
- When the compilation is done, you can read the temperature and humidity data from the terminal.
