Eclipse Mraa - Low Level Skeleton Library for Communication on GNU/Linux platforms ============================================================================= Eclipse Mraa (Libmraa) is a C/C++ library with bindings to Java, Python and JavaScript to interface with the IO on Galileo, Edison & other platforms, with a structured and sane API where port names/numbering matches the board that you are on. Use of libmraa does not tie you to specific hardware with board detection done at runtime you can create portable code that will work across the supported platforms. The intent is to make it easier for developers and sensor manufacturers to map their sensors & actuators on top of supported hardware and to allow control of low level communication protocol by high level languages & constructs. The MRAA project is joining the Eclipse Foundation as an Eclipse IoT project. You can read more about this [here](https://projects.eclipse.org/proposals/eclipse-mraa).

Install on Arch Linux --------------------- There is an AUR package for mraa here: https://aur.archlinux.org/packages/mraa Install on openSUSE ------------------- ```bash REPO="openSUSE_Tumbleweed" if test "$(arch)" == "aarch64"; then REPO="openSUSE_Factory_ARM" fi sudo zypper ar http://download.opensuse.org/repositories/hardware/$REPO/hardware.repo sudo zypper in mraa ``` Install on Fedora Linux ----------------------- There is an mraa package in the main Fedora repository so it can be dnf installed in all recent Fedora releases. The Node.js and Python 3 bindings are packaged as separate packages. ```bash sudo dnf install mraa nodejs-mraa python3-mraa ``` Installing for Node.js only --------------------------- > Note: Node.js 7.0.0+ is not currently supported unless compiling with a patched vesion of SWIG. See the corresponding section and document below. You can also install just the node.js mraa module by using npm. You will need a C++ compiler and the node development headers, however it's not required to have SWIG installed. This works for node versions 6.x.x and prior. ```bash npm install mraa ``` Note that installing mraa in this way builds mraa without json-c so you cannot use mraa_init_json_platform(). Also building this way means the mraa.node includes a static version of libmraa rather than relying on a dynamic library in /usr/lib. Subplatforms (i.e. Firmata) have to be added manually with this kind of install from your application, as shown in [this example](examples/javascript/firmata.js). Compiling ========= See documentation on [building](../master/docs/building.md) Examples ======== See the [examples](../../tree/master/examples) available for various languages Debugging ========= Sometimes it just doesn't want to work, let us try and help you, you can file issues in github or join us in #mraa on freenode IRC, hang around for a little while because we're not necessarily on 24/7, but we'll get back to you! Have a glance at our [debugging](../master/docs/debugging.md) page too. API Documentation ================= Contact Us ========== To ask questions either file issues in github or send emails on our [mailing list](https://lists.01.org/mailman/listinfo/mraa). You might also catch us on the mraa channel on freenode IRC. See the [Contribution](CONTRIBUTING.md) documentation for more details. Changelog ========= Version changelog [here](docs/changelog.md).
