Tiny CLI and script interpreter for embedded systems. 2KB flash, zero malloc, multi-instance. Interactive command line with scriptable dispatch, single-key menus, and pass-through mode.
Timestamp service for ESP32 that works without a dedicated RTC module. Starts from build time on every boot, then corrects via SNTP sync or manual set — whichever suits the application. All corrections are explicit and observable via jump callbacks, safe for logging systems.
