Getting Started With Zephyr: Writing Data to EEPROM
In this blog post, I show how to implement a Zephyr application to interact with EEPROM. I show how the Zephyr device driver model allows application writers to be free of the underlying implementation details. Unfortunately, the application didn't work as expected, and I'm still troubleshooting the cause.
Summary
Mohammed Billoo demonstrates how to implement a Zephyr application that interacts with EEPROM, illustrating how Zephyr's device driver model abstracts hardware details from the application. The post covers device tree setup, using the Zephyr EEPROM API, and the author's troubleshooting attempts after the example failed to behave as expected.
Key Takeaways
- Understand Zephyr's device driver model and how it abstracts EEPROM hardware from application code.
- Configure device tree entries and overlays to expose an EEPROM device to a Zephyr application.
- Use Zephyr's EEPROM API to perform basic read and write operations over I2C/SPI.
- Troubleshoot EEPROM access with Zephyr logging, bus inspection, and driver verification techniques.
