Adds signal handling for graceful shutdown via SIGINT and SIGTERM.
Updates the control loop to be interruptible, allowing for a clean exit when a shutdown signal is received.
Changes the node state management to use an enum for clarity and better control the run states (starting, running, stopping, stopped).
The heartbeat is stopped when the node is stopping or stopped.
Also updates the line request to force an inactive state when claiming the pin.
Also updates the version number.
Introduces a heartbeat mechanism to the robot node using GPIO.
This allows for external monitoring of the node's active state.
The heartbeat is implemented using a GPIO pin that toggles
at a regular interval, indicating that the system is running.
Updates CMakeLists to link the project with gpiod libraries
staged locally.
Adds .gitignore entries for local dependencies and PC build directories.
Introduces a basic structure for the robot control node. This includes:
- A central brain component that manages the robot's logic.
- A state management system using a singleton to ensure thread-safe access to shared data.
- A simple main loop that can be started and stopped.
- Initial CMakeLists.txt and gitignore configurations.
This provides a foundation for implementing robot control logic.
