Detailed Description

ESP32 CAN (TWAI) implementation for the HardFOC system - ESP-IDF v5.5 Compatible.

This file provides a comprehensive CAN bus implementation for the ESP32 microcontroller family using modern ESP-IDF v5.5+ TWAI node-based APIs. The implementation provides advanced features for ESP32-C6 with external SN65 transceivers.

Key Features Implemented:

• ESP-IDF v5.5+ handle-based TWAI node API
• ESP32-C6 compatible TWAI controller support
• Event-driven callback-based message reception
• Advanced acceptance filtering (single/dual mask modes)
• Comprehensive error detection and bus recovery
• Advanced bit timing configuration for various baud rates
• Thread-safe operations with proper resource management
• Support for external SN65 CAN transceivers
• Comprehensive diagnostics and performance monitoring
