Cross-platform chrono-based logging library for embedded systems. Provides thread-safe, timestamped logs with module tagging and RTOS awareness. Works on ESP-IDF, STM32 HAL, Arduino, and Linux/Windows.
TinyGPS++ — compact NMEA-0183 parser ported to ESP-IDF. No Arduino dependency. millis() is implemented via esp_timer_get_time(). Parses GGA and RMC sentences; exposes location, date, time, speed, course, altitude, satellite count, HDOP, and arbitrary custom terms.
