Detailed Description

ESP32 UART implementation for the HardFOC system.

This file provides a comprehensive UART implementation for ESP32 variants using the built-in UART peripheral. The implementation supports multiple ports, configurable baud rates and data formats, hardware flow control, interrupt-driven operation, pattern detection, and comprehensive error handling.

Note

This implementation is designed for all ESP32 variants using ESP-IDF v5.5+

Supports ESP32-C6, ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C2, ESP32-H2

Each EspUart instance represents a single UART port

Higher-level applications should instantiate multiple EspUart objects for multi-port boards
