Jelle van Kraaij developed a 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. Working primarily in C, Jelle introduced the ds18b20_new_single_device function and updated the ds18b20_send_command API to support this streamlined mode, addressing a common use case in embedded systems and hardware integration. Alongside the new feature, Jelle improved code quality by applying pre-commit style fixes and aligning versioning, which enhanced CI reliability. The work culminated in a 0.1.2 release, reflecting a focused and well-maintained approach to device driver development.
