$ show micro-ROS/micro_ros_setup
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.
The LLM identified 2 files worth highlighting for reuse:
Reads a YAML repository list from stdin and a package whitelist from a given file, then outputs only those repositories whose keys appear in the whitelist. This is a self-contained, reusable utility for filtering YAML structures based on a simple keep-list, independent of the micro-ROS context.
A reusable shell script that strips ROS 2 workspace paths from LD_LIBRARY_PATH, CMAKE_PREFIX_PATH, PYTHONPATH, and PATH to avoid cross-compilation conflicts. It implements a clean separation between system paths and workspace-specific paths, a pattern applicable to any cross-compilation or multi-workspace environment.
