This project explores various Linux device driver development approaches for the BeagleBone Black single-board computer. It emphasizes user-space interaction techniques and leverages the device tree and sysfs mechanisms.
Implemented Drivers:
- Pseudo Character Device Driver: A fundamental driver providing a basic user-space interface.
- Pseudo Character Platform Driver: Utilizes the platform bus framework for more advanced interactions.
- Pseudo Character Device Tree and Overlay: Defines and configures the device node using the device tree and overlays.
- Pseudo Character Device sysfs: Exposes attributes and functionalities through the sysfs filesystem.
- GPIO sysfs for BeagleBone Black: Demonstrates control and interaction with GPIO pins via sysfs.
Project Benefits:
- Hands-on Learning: Practical experience with different Linux device driver development concepts.
- Driver Framework Understanding: Explores platform bus and device tree mechanisms for driver configuration.
- User-Space Interaction: Showcases techniques for exposing driver functionalities to user-space applications using sysfs.
- BeagleBone Black Expertise: Deepens understanding of the BeagleBone Black's hardware and software architecture.
Technical Skills Highlighted:
- Linux Device Driver Development: Proficiency in writing and implementing Linux device drivers.
- Device Tree and Overlay Knowledge: Understanding of device tree structure and overlays for driver configuration.
- sysfs Interfacing: Ability to expose driver functionalities through the sysfs filesystem.
- BeagleBone Black Hardware Interaction: Knowledge of the BeagleBone Black's GPIO capabilities and sysfs control.
