Developed and delivered a new DS18B20 Single-Device Mode for the espressif/esp-bsp repository, enabling operation with a single sensor on the 1-Wire bus without requiring device enumeration. This work involved implementing the ds18b20_new_single_device function and updating the ds18b20_send_command API, all written in C with a focus on embedded systems and device driver development. The release included a version bump to 0.1.2 and comprehensive documentation updates in the CHANGELOG. Additional efforts addressed code quality by applying pre-commit style fixes, which improved CI reliability and ensured the repository’s readiness for stable release and ongoing hardware integration.
