MAVLink

MAVLink -- Micro Air Vehicle Message Marshalling Library.

MAVLink is a very lightweight, header-only message library for communication between drones and/or ground control stations. It consists primarily of message-set specifications for different systems ("dialects") defined in XML files, and Python tools that convert these into appropriate source code for supported languages. There are additional Python scripts providing examples and utilities for working with MAVLink data.

Tip MAVLink is very well suited for applications with very limited communication bandwidth. Its reference implementation in C is highly optimized for resource-constrained systems with limited RAM and flash memory. It is field-proven and deployed in many products where it serves as interoperability interface between components of different manufacturers.

Quick start

Generate C headers

To install the minimal MAVLink environment on Ubuntu LTS 20.04 or 22.04, enter the following on a terminal:

# Dependencies
sudo apt install python3-pip

# Clone mavlink into the directory of your choice
git clone https://github.com/mavlink/mavlink.git --recursive
cd mavlink

python3 -m pip install -r pymavlink/requirements.txt

You can then build the MAVLink2 C-library for message_definitions/v1.0/common.xml from the /mavlink directory as shown:

python3 -m pymavlink.tools.mavgen --lang=C --wire-protocol=2.0 --output=generated/include/mavlink/v2.0 message_definitions/v1.0/common.xml

Use from cmake

To include the headers in cmake, install them locally, e.g. into the directory install:

cmake -Bbuild -H. -DCMAKE_INSTALL_PREFIX=install -DMAVLINK_DIALECT=common -DMAVLINK_VERSION=2.0
cmake --build build --target install

Then use find_package to get the dependency in CMakeLists.txt:

find_package(MAVLink REQUIRED)

add_executable(my_program my_program.c)

target_link_libraries(my_program PRIVATE MAVLink::mavlink)

And pass the local install directory to cmake (adapt to your directory structure):

cd ../my_program
cmake -Bbuild -H. -DCMAKE_PREFIX_PATH=../mavlink/install

For a full example, check examples/c.

Note: even though we use target_link_libraries in cmake, it doesn't actually "link" to MAVLink as it's just a header-only library.

Other instructions

Instructions for using the C libraries are then covered in Using C MAVLink Libraries (mavgen).

Note: Installing the MAVLink Toolchain explains how to install MAVLink on other Ubuntu platforms and Windows, while Generating MAVLink Libraries explains how to build MAVLink for the other programming languages supported by the project. The sub-topics of Using MAVLink Libraries explain how to use the generated libraries.

Build Status

MAVLink -- Micro Air Vehicle Message Marshalling Library. The current protocol version is v2.

This is a library for lightweight communication between drones and/or ground control stations. It allows for defining messages within XML files, which then are converted into appropriate source code for different languages. These XML files are called dialects, most of which build on the common dialect provided in common.xml.

The initial experimental MAVLink was created 2008 when the term drone was not used yet to describe small vehicles for consumer use.

The MAVLink protocol performs byte-level serialization and so is appropriate for use with any type of radio modem.

This repository is largely Python scripts that convert XML files into language-specific libraries. There are additional Python scripts providing examples and utilities for working with MAVLink data. These scripts, as well as the generated Python code for MAVLink dialects, require Python 2.7 or greater.

Requirements

  • Python 2.7+
    • Tkinter (if GUI functionality is desired)

Installation

  1. Clone into a user-writable directory. Make sure to use the git "--recursive" option since pymavlink is a submodule. Alternately, run "git submodule init" and "git submodule update" after cloning to get pymavlink.
  2. Add the repository directory to your PYTHONPATH
  3. Generate MAVLink parser files following the instructions in the next section AND/OR run included helper scripts described in the Scripts/Examples secion.

Generating Language-specific Source Files

Language-specific files can be generated via a Python script from the command line or using a GUI. If a dialect XML file has a dependency on another XML file, they must be located in the same directory. Since most MAVLink dialects depend on the common messageset, it is recommend that you place your dialect with the others in /message_definitions/v1.0/.

Available languages are:

  • C
  • C#
  • Java
  • JavaScript
  • Lua
  • Python, version 2.7+

mavgenerate.py is a header generation tool GUI written in Python. It requires Tkinter, which is only included with Python on Windows, so it will need to be installed separately on non-Windows platforms. It can be run from anywhere using Python's -m argument:

$ python -m mavgenerate

From the command line

mavgen.py is a command-line interface for generating a language-specific MAVLink library. This is actually the backend used by mavgenerate.py. After the mavlink directory has been added to the Python path, it can be run by executing from the command line:

$ python -m pymavlink.tools.mavgen

Usage

Using the generated MAVLink dialect libraries varies depending on the language, with language-specific details below:

C

To use MAVLink, include the mavlink.h header file in your project:

#include <mavlink.h>

Do not include the individual message files. In some cases you will have to add the main folder to the include search path as well. To be safe, we recommend these flags:

$ gcc -I mavlink/include -I mavlink/include/<your message set, e.g. common>

The C MAVLink library utilizes a channels metaphor to allow for simultaneous processing of multiple MAVLink streams in the same program. It is therefore important to use the correct channel for each operation as all receiving and transmitting functions provided by MAVLink require a channel. If only one MAVLink stream exists, channel 0 should be used by using the MAVLINK_COMM_0 constant.

Receiving

MAVLink reception is then done using mavlink_helpers.h:mavlink_parse_char().

Transmitting

Transmitting can be done by using the mavlink_msg_*_pack() function, where one is defined for every message. The packed message can then be serialized with mavlink_helpers.h:mavlink_msg_to_send_buffer() and then writing the resultant byte array out over the appropriate serial interface.

It is possible to simplify the above by writing wrappers around the transmitting/receiving code. A multi-byte writing macro can be defined, MAVLINK_SEND_UART_BYTES(), or a single-byte function can be defined, comm_send_ch(), that wrap the low-level driver for transmitting the data. If this is done, MAVLINK_USE_CONVENIENCE_FUNCTIONS must be defined.

Scripts/Examples

This MAVLink library also comes with supporting libraries and scripts for using, manipulating, and parsing MAVLink streams within the pymavlink, pymav link/tools, and pymavlink/examples directories.

The scripts have the following requirements: * Python 2.7+ * mavlink repository folder in PYTHONPATH * Write access to the entire mavlink folder. * Your dialect's XML file is in message_definitions/*/

Running these scripts can be done by running Python with the '-m' switch, which indicates that the given script exists on the PYTHONPATH. This is the proper way to run Python scripts that are part of a library as per PEP-328 (and the rejected PEP-3122). The following code runs mavlogdump.py in /pymavlink/tools/ on the recorded MAVLink stream test_run.mavlink (other scripts in /tools and /scripts can be run in a similar fashion):

$ python -m pymavlink.tools.mavlogdump test_run.mavlink

License

MAVLink is licensed under the terms of the Lesser General Public License (version 3) of the Free Software Foundation (LGPLv3). The C-language version of MAVLink is a header-only library which is generated as MIT-licensed code. MAVLink can therefore be used without limits in any closed-source application without publishing the source code of the closed-source application.

Note that there are two incompatible versions of the MAVLink protocol: v0.9 and v1.0. Most programs, including QGroundControl, have switched over to v1.0. The v0.9 protocol is DEPRECATED and should only be used to maintain backwards compatibility where necessary.

Requirements

  • Python 2.7+
    • Tkinter (if GUI functionality is desired)

License

MAVLink is licensed under the terms of the Lesser General Public License (version 3) of the Free Software Foundation (LGPLv3). The C-language version of MAVLink is a header-only library, and as such compiling an application with it is considered "using the library", not a derived work.

MAVLink -- Micro Air Vehicle Message Marshalling Library.

This is a library for lightweight communication between Micro Air Vehicles (swarm) and/or ground control stations. It allows for defining messages within XML files, which then are converted into appropriate source code for different languages. These XML files are called dialects, most of which build on the common dialect provided in common.xml.

The MAVLink protocol performs byte-level serialization and so is appropriate for use with any type of radio modem.

This repository is largely Python scripts that convert XML files into language-specific libraries. There are additional Python scripts providing examples and utilities for working with MAVLink data. These scripts, as well as the generated Python code for MAVLink dialects, require Python 2.7 or greater.

Note that there are two incompatible versions of the MAVLink protocol: v0.9 and v1.0. Most programs, including QGroundControl, have switched over to v1.0. The v0.9 protocol is DEPRECATED and should only be used to maintain backwards compatibility where necessary.

Requirements

  • Python 2.7+
    • Tkinter (if GUI functionality is desired)

Installation

  1. Clone into a user-writable directory.
  2. Add the repository directory to your PYTHONPATH

Generating Language-specific Source Files

Language-specific files can be generated via a Python script from the command line or using a GUI. If a dialect XML file has a dependency on another XML file, they must be located in the same directory. Since most MAVLink dialects depend on the common messageset, it is recommend that you place your dialect with the others in /message_definitions/v1.0/.

Available languages are:

  • C
  • C#
  • JavaScript
  • Lua
  • Python, version 2.7+

mavgenerate.py is a header generation tool GUI written in Python. It requires Tkinter, which is only included with Python on Windows, so it will need to be installed separately on non-Windows platforms. It can be run from anywhere using Python's -m argument:

$ python -m mavgenerate

From the command line

mavgen.py is a command-line interface for generating a language-specific MAVLink library. This is actually the backend used by mavgenerate.py. After the mavlink directory has been added to the Python path, it can be run by executing from the command line:

$ python -m pymavlink.generator.mavgen

Usage

Using the generated MAVLink dialect libraries varies depending on the language, with language-specific details below:

C

To use MAVLink, include the mavlink.h header file in your project:

#include <mavlink.h>

Do not include the individual message files. In some cases you will have to add the main folder to the include search path as well. To be safe, we recommend these flags:

$ gcc -I mavlink/include -I mavlink/include/<your message set, e.g. common>

The C MAVLink library utilizes a channels metaphor to allow for simultaneous processing of multiple MAVLink streams in the same program. It is therefore important to use the correct channel for each operation as all receiving and transmitting functions provided by MAVLink require a channel. If only one MAVLink stream exists, channel 0 should be used by using the MAVLINK_COMM_0 constant.

Receiving

MAVLink reception is then done using mavlink_helpers.h:mavlink_parse_char().

Transmitting

Transmitting can be done by using the mavlink_msg_*_pack() function, where one is defined for every message. The packed message can then be serialized with mavlink_helpers.h:mavlink_msg_to_send_buffer() and then writing the resultant byte array out over the appropriate serial interface.

It is possible to simplify the above by writing wrappers around the transmitting/receiving code. A multi-byte writing macro can be defined, MAVLINK_SEND_UART_BYTES(), or a single-byte function can be defined, comm_send_ch(), that wrap the low-level driver for transmitting the data. If this is done, MAVLINK_USE_CONVENIENCE_FUNCTIONS must be defined.

Scripts/Examples

This MAVLink library also comes with supporting libraries and scripts for using, manipulating, and parsing MAVLink streams within the pymavlink, pymavlink/tools, and pymavlink/examples directories.

Requirements

  • Python 2.7+
  • mavlink repository folder in PYTHONPATH
  • Write access to the entire mavlink folder.
  • Your dialect's XML file is in message_definitions/*/

Running these scripts can be run by listing the folder hierarchy for the script. The following code runs mavlogdump.py in /pymavlink/tools/ on the recorded MAVLink stream test_run.mavlink:

$ python -m pymavlink.tools.mavlogdump test_run.mavlink

License

MAVLink is licensed under the terms of the Lesser General Public License (version 3) of the Free Software Foundation (LGPLv3). The C-language version of MAVLink is a header-only library, and as such compiling an application with it is considered "using the library", not a derived work. MAVLink can therefore be used without limits in any closed-source application without publishing the source code of the closed-source application.

MAVLink -- Micro Air Vehicle Message Marshalling Library.

This is a library for lightweight communication between Micro Air Vehicles (swarm) and/or ground control stations. It serializes C-structs for serial channels and can be used with any type of radio modem.

Messages definitions are created in XML, and then converted into C header files.

Generating Headers

Header files can be generated either with mavgen, or within QGroundControl.

With mavgen

mavgen is a header generation tool written in python, which is included with MAVLink. It can be used directly or via the generator.py GUI. To use the GUI, run:

python mavgenerate.py

If you would rather use mavgen from the command line see pymavlink\generator\mavgen.py.

With QGroundControl

To generate/update packets, select mavlink_standard_message.xml in the QGroundControl station settings view, select mavlink/include as the output directory and click on "Save and Generate". You will find the newly generated/updated message_xx.h files in the mavlink/include/generated folder.

Usage

To use MAVLink, include the mavlink.h header file in your project:

#include <mavlink.h>

Do not include the individual message files. In some cases you will have to add the main folder to the include search path as well. To be safe, we recommend these flags:

gcc -I mavlink/include -I mavlink/include/<your message set, e.g. common>

License

MAVLink is licensed under the terms of the Lesser General Public License of the Free Software Foundation (LGPL). As MAVLink is a header-only library, compiling an application with it is considered "using the libary", not a derived work. MAVLink can therefore be used without limits in any closed-source application without publishing the source code of the closed-source application.

This is a library for lightweight communication between drones and/or ground control stations. It allows for defining messages within XML files, which then are converted into appropriate source code for different languages. These XML files are called dialects, most of which build on the common dialect provided in common.xml.

The initial experimental MAVLink was created 2008 when the term drone was not used yet to describe small vehicles for consumer use.

The MAVLink protocol performs byte-level serialization and so is appropriate for use with any type of radio modem.

This repository is largely Python scripts that convert XML files into language-specific libraries. There are additional Python scripts providing examples and utilities for working with MAVLink data. These scripts, as well as the generated Python code for MAVLink dialects, require Python 2.7 or greater.

Requirements

  • Python 2.7+
    • Tkinter (if GUI functionality is desired)

Installation

  1. Clone into a user-writable directory.
  2. Add the repository directory to your PYTHONPATH
  3. Generate MAVLink parser files following the instructions in the next section AND/OR run included helper scripts described in the Scripts/Examples secion.

Generating Language-specific Source Files

Language-specific files can be generated via a Python script from the command line or using a GUI. If a dialect XML file has a dependency on another XML file, they must be located in the same directory.

Using the generated MAVLink dialect libraries varies depending on the language, with language-specific details below:

To use MAVLink, include the mavlink.h header file in your project:

#include <mavlink.h>

Do not include the individual message files. In some cases you will have to add the main folder to the include search path as well. To be safe, we recommend these flags:

Scripts/Examples

This MAVLink library also comes with supporting libraries and scripts for using, manipulating, and parsing MAVLink streams within the pymavlink, pymav link/tools, and pymavlink/examples directories.

The scripts have the following requirements: * Python 2.7+ * mavlink repository folder in PYTHONPATH * Write access to the entire mavlink folder. * Your dialect's XML file is in message_definitions/*/

Running these scripts can be done by running Python with the '-m' switch, which indicates that the given script exists on the PYTHONPATH. This is the proper way to run Python scripts that are part of a library as per PEP-328 (and the rejected PEP-3122). The following code runs mavlogdump.py in /pymavlink/tools/ on the recorded MAVLink stream test_run.mavlink (other scripts in /tools and /scripts can be run in a similar fashion):

$ python -m pymavlink.tools.mavlogdump test_run.mavlink

License

MAVLink is licensed under the terms of the Lesser General Public License (version 3) of the Free Software Foundation (LGPLv3). The C-language version of MAVLink is a header-only library which is generated as MIT-licensed code. MAVLink can therefore be used without limits in any closed-source application without publishing the source code of the closed-source application.

Build Status

MAVLink -- Micro Air Vehicle Message Marshalling Library.

MAVLink is a very lightweight, header-only message library for communication between drones and/or ground control stations. It consists primarily of message-set specifications for different systems ("dialects") defined in XML files, and Python tools that convert these into appropriate source code for supported languages. There are additional Python scripts providing examples and utilities for working with MAVLink data.

Tip MAVLink is very well suited for applications with very limited communication bandwidth. Its reference implementation in C is highly optimized for resource-constrained systems with limited RAM and flash memory. It is field-proven and deployed in many products where it serves as interoperability interface between components of different manufacturers.
