AgIsoStack-Arduino is a lightweight adaptation of the AgIsoStack++ library for use with Arduino-based hardware, providing ISOBUS (ISO 11783) and SAE J1939 CAN communication functionality. It supports features such as address claiming, virtual terminal (VT) client, task controller client, guidance messaging, and fast packet transport — primarily targeting Teensy boards with future support planned for ESP32. Designed for embedded systems, it enables agricultural machines and implements to communicate seamlessly on off-highway vehicle networks using standardized protocols.
