Eclipse Mraa - Low Level I/O Communications Library for GNU/Linux platforms

===========================================================================

Eclipse Mraa (Libmraa) is a C/C++ library with bindings to Java, Python and JavaScript

to interface with the I/O pins and buses on various IoT and Edge platforms, with a

structured and sane API where port names/numbering match the board that you are on.

Use of libmraa does not tie you to specific hardware. Since 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 an Eclipse IoT project. A detailed project description can be found [here](https://projects.eclipse.org/proposals/eclipse-mraa).

Installing on your board

========================

Installing on Ubuntu

--------------------

Here is a PPA for installing on Ubuntu Xenial or Bionic:

https://launchpad.net/~mraa/+archive/ubuntu/mraa

```bash

sudo add-apt-repository ppa:mraa/mraa

sudo apt-get update

sudo apt-get install libmraa2 libmraa-dev libmraa-java python-mraa python3-mraa node-mraa mraa-tools

```

Running MRAA tools or applications on Ubuntu systems requires elevated permissions

(e.g. run with `sudo`).

Install on Arch Linux

---------------------

There is an AUR package for mraa here: https://aur.archlinux.org/packages/mraa

Install on openSUSE or SLE

---------------------------

For the latest versions of openSUSE and SLE the project is distributed via

native repositories and can be installed by developers with:

```bash

sudo zypper install mraa mraa-devel

```

For ARM boards use:

```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

```

A full list of packages and instructions for installing MRAA for various openSUSE releases

can be found [here](https://software.opensuse.org/package/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 Red Hat Enterprise Linux, CentOS and Other Linux Distributions

---------------------------

The MRAA project does not currently distribute official binaries for RHEL

or CentOS so developers will have to compile the project from sources as

described in the next section.

For testing and development purposes it may be possible to share and install

.deb and .rpm packages across similar Linux builds.

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.
