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.
WiFi lifecycle manager for ESP-IDF. Handles scanning, credential-based reconnection, and BLE provisioning as a single owned component — including disconnect recovery, multi-AP priority, time-window deadlines, retry-in-place provisioning and NVS-persisted credentials with LRU ranking. Other components observe state through an event interface and never touch esp_wifi directly.
