micro_ros_setup is a ROS 2 package providing shell scripts and configuration to automate the creation, configuration, build, and flashing of micro-ROS firmware for embedded platforms. It orchestrates the cross-compilation of the micro-ROS client library (rclc, rmw_microxrcedds, etc.) against multiple RTOS targets (FreeRTOS, Zephyr, Android, host Linux) using colcon and platform-specific toolchains. The package acts as a build system integration layer: it creates a development workspace cloned from ROS 2 and micro-ROS repositories, applies platform-specific colcon metadata, handles transport selection (UART, UDP, USB), and builds/flashes the firmware binaries. It is not a running application but a set of tools that must be invoked from a ROS 2 workspace after building the package itself.
