Developed and integrated support for the Waveshare 3.97-inch E-Paper Display within the esphome/esphome repository, enabling new hardware compatibility for ESPHome dashboards. This work involved designing an SPI-based e-paper driver using Python, with a focus on embedded systems and hardware integration. The implementation allows users to build energy-efficient, high-contrast IoT interfaces, expanding the practical applications of ESPHome for low-power display solutions. The feature was delivered as a focused, well-scoped commit and linked to a pull request, demonstrating a methodical approach to code contribution and collaboration. No bug fixes were recorded during this period, emphasizing targeted feature development.
