A collection of lightweight, "header-only" C++ utilities for IoT/embedded applications on ESP32.

Originally developed for the Arduino framework :

• Some components may depend on Arduino (String, Serial, digitalWrite...)
• Some may use FreeRTOS or ESP-IDF primitives (peripherals, timers, tasks...)
• No external dependencies to the ESP32 Arduino core except ArduinoJson for the logger library

• AsyncSerial : a thread-safe UART library, offering a drop-in replacement to the Serial API with efficient management of concurrent access.
• AsyncWire : a thread-safe I2C library, offering a drop-in replacement to the Wire API with intuitive Wire sequences declaration.
• LedBlinker: a simple and flexible Arduino library for controlling LED blinking patterns with FreeRTOS support.
• MultiLogger: a thread-safe logging system allowing simple management of various log ouputs (UART, SD card, JSON...)
• PulseCounter: a high-performance pulse counting library using ESP32's hardware PCNT module & timer-based polling
• SerialConverter: a simple utility class for converting between raw bytes and common serial formats (Hex, Base64)
• SimpleTimer: a lightweight and versatile timer class for ESP32
