ROS 2 Humble Hawksbill Released!

rclc - The ROS 2 C-API for micro-controllers

The rclc package complements the ROS Client Support Library (rcl) to provide a complete ROS 2 client library for the C programming language. That is, rclc does not add a new layer of types on top of rcl (like rclcpp and rclpy do) but only provides convenience functions that ease the programming with the rcl types.

With Humble, it supports not only all communication types like subscriptions, timers, services, clients etc. but also parameters, actions and lifecycle. It comes with its own Executor enabling more deterministic and real-time execution management. It serves as a fully-compliant ROS 2 programming interface for micro-ROS applications on micro-controllers. An overview, concepts, tutorials, supported micro-controllers and RTOSes can be found at micro.ros.org.

Check out the Tutorials today and get started with first applications on your micro-controller on https://github.com/micro-ROS/.
