AgIsoStack++ simplifies implementing ISOBUS functionalities by providing a transparent and well-documented library. This allows you to concentrate on your application, without getting bogged down in rules defined by standards and guidelines.

- Platform independent C++11 library, from Linux, Windows and macOS PCs down to ESP32 microcontrollers
- The complete backbone of the ISO11783 and J1939 standards: address claiming, transport protocol (TP), extended transport protocol (ETP) and PGN requests
- Virtual Terminal Client (Universal Terminal), plus a Virtual Terminal Server base
- Auxiliary control (AUX-N)
- Task Controller Client and Server, with a Device Descriptor Object Pool (DDOP) builder
- ISOBUS shortcut button (ISB)
- Diagnostic protocol (DM1, DM2, DM3, DM11, DM13, DM22, ECU and software identification)
- Control function functionalities, heartbeat, language command, maintain power and time/date messages
- Common guidance and speed messages (wheel-based, ground-based and machine selected speed)
- NMEA 2000 Fast Packet Protocol and common NMEA 2000 messages
- Hardware drivers for many common CAN controllers, and a virtual CAN driver for testing without hardware
ISOBUS (based on the ISO-11783 standard) defines how agricultural machinery should communicate with each other on a CANbus network. Cross compatibility is achieved when different manufacturers carefully follow this standard when developing their devices. This means that a tractor from one manufacturer can communicate with an implement from another manufacturer, and vice versa.
AgIsoStack++ provides an easy-to-use interface for your application to communicate on the ISOBUS network in a compliant manner, without the need to worry about the details of the standard. The library is written in C++11 and uses the STL whenever possible. It is designed to be easy to understand and is fully documented.
Check out the tutorial website for information on ISOBUS basics, how to download this library, and how to use it. The tutorials contain in-depth examples and explanations to help get your ISOBUS or J1939 project going quickly. A good first stop is The ISOBUS Hello World.
The library is built from source with CMake 3.16 or newer. The quickest way to pull it into a CMake project is FetchContent:
include(FetchContent)
FetchContent_Declare(
AgIsoStack
GIT_REPOSITORY https://github.com/Open-Agriculture/AgIsoStack-plus-plus.git
GIT_TAG main # Pin a commit hash for reproducible builds
)
FetchContent_MakeAvailable(AgIsoStack)
find_package(Threads)
target_link_libraries(<your target> PRIVATE isobus::Isobus isobus::HardwareIntegration isobus::Utility Threads::Threads)A CAN driver is picked for your OS by default (SocketCAN on Linux, PEAK PCAN-Basic on Windows, MacCAN PCAN on macOS). Choose another with -DCAN_DRIVER=<driver>, or several with -DCAN_DRIVER="<driver1>;<driver2>". The installation guide also covers git submodules, and the ESP32 PlatformIO tutorial covers microcontrollers.
git clone https://github.com/Open-Agriculture/AgIsoStack-plus-plus.git
cd AgIsoStack-plus-plus
cmake -S . -B build -DBUILD_EXAMPLES=ON -DBUILD_TESTING=ON
cmake --build build --config Debug
cd build && ctest -C Debug --output-on-failureThe library itself is C++11, but the unit tests need a C++17 compiler.
On Linux, examples that use the default SocketCAN driver open the vcan0 interface, so you can try them without any CAN hardware:
sudo modprobe vcan
sudo ip link add vcan0 type vcan
sudo ip link set vcan0 upSee examples/README.md for installing the library as a CMake package and building a single example against it.
If you are integrating with our library to create an ISO11783 or J1939 application and are not selling your software or device containing that software for-profit, then you are welcome to use our manufacturer number in your application.
If you are creating such an application for sale as a for-profit company, then we ask that you please obtain your own manufacturer code from SAE instead of using ours.
Our manufacturer code is 1407 (decimal).

Contributions are welcome! Read CONTRIBUTING.md for the code style, formatting and testing rules a pull request has to meet. It also explains how to install docs/pre-commit-hook.sh, which formats your changes before each commit.
These Open-Agriculture projects are built with, or alongside, AgIsoStack++:
- AgIsoVirtualTerminal - an ISO 11783-6 Virtual Terminal server for the desktop
- AgIsoDDOPGenerator - a desktop editor for Device Descriptor Object Pools
- AgIsoTerminalDesigner - an editor for Virtual Terminal object pools
- AgIsoStack-rs - a Rust implementation of the stack
