Detailed Description

Advanced MCU-integrated SPI controller implementation with ESP32C6/ESP-IDF v5.5+ features.

This header provides a comprehensive SPI implementation that utilizes all the advanced features available in ESP-IDF v5.5+ for ESP32C6, including DMA acceleration, octal/quad modes, advanced timing control, multi-device management, power optimization, and comprehensive error handling. The implementation supports both master and slave modes with extensive configuration options for high-performance and low-power applications.

Key ESP32C6/ESP-IDF v5.5+ Features Supported:

• High-speed SPI Master with DMA support (up to 80MHz)
• Multiple clock sources (APB, XTAL) for power optimization
• IOMUX optimization for high-frequency operations
• Transaction queuing with interrupt and polling modes
• Comprehensive error handling and status reporting
• Thread-safe multi-device management on single bus
• Advanced timing control with input delay compensation
• Transaction callbacks for custom handling
