Alibabacloud.com offers a wide variety of articles about raspberry pi development kit, easily find your raspberry pi development kit information here online.
First, install the Raspberry Pi and Arduino development environment

2. Building a Raspberry
For many IoT applications, using a Raspberry Pi to build an intelligent gateway is no longer appropriate, but the market of those "XX smart", "XX center" direct seconds kill it!Hardware needs to be extended: SD card, WiFi, Bluetooth, USB hub,tft display.What software is needed: scripting engine, remote login service, Web server, messaging server, processing server, forwarding server, Smart Display software,

Note: Uinput's key value is generally uinput. Key_xx (XX is the key, such as the letter A, is uinput. KEY_A)

prove that Snappy is a system for cloud computing, especially for Iot.
Snappy can also run on other clouds such as Amazon EC2, Microsoft Azure, and Google's Compute Engine. It can also be virtualized on KVM, Virtuabox, and vagrant. Canonical Ubuntu has embraced heavyweight players such as Microsoft, Google, Docker, and OpenStack, and has reached partnerships with small projects. In addition to some startups, such as Ninja Sphere and Erle Robotics, there are also some

Cross-compiled Raspberry Pi 2 kernel in CentOS
Cross-compilation toolchain in CentOS 6.6 x64 requires glibc-2.14 support (x86 is not needed), so first install the glibc-2.14
Install the relevant compilation tools before installation. Here I will install the entire group directly.
Yum groupinstall "Development tools"-y
Download the glibc-2.14 source code, compile,
software package is ready and can be released;
Iii. Cross-compiling source code
1. Environment
Ubuntu
2. Install Raspberry Pi cross compiling tool
Step1. download Raspberry Pi cross compiler tool https://github.com/raspberrypi/tools
Step 2: place the source code in a folder that users can share, such as/usr/tools.

ShieldsA Few other cool maker things worth pointing out is Windows Remote Arduino and Virtual Arduino Shields. Remote Arduino lets your Arduino from your Windows machine using the Firmata protocol. Then your can reach out to an Arduino device and give it commands from a Windows Universal app. The virtual Arduino Shields lets you with a Windows Phone as a well, just that, Virtual Shields. Shields for the Arduino can add up and when do you ' re prototyping-not want-to-shell out for a Gyro or GPS.
