Compact fixed-point math library for embedded systems. Integer-only with caller-selectable radix. Trig, log/exp, sqrt, hypot, wave generators, ADSR, and 2D transforms. Zero dependencies.
Accurate system time and timestamp service for ESP32 with SNTP sync and manual control. Provides explicit, deterministic time management — no hidden updates, no background sync. All time changes are user-initiated, observable via jump callbacks, and safe for logging systems.
