Detailed Description

ESP32C6 LEDC (PWM) controller implementation for the HardFOC system.

This header provides a comprehensive PWM implementation for ESP32C6 using the LEDC (LED Controller) peripheral which provides high-resolution PWM generation. The implementation supports multiple channels, configurable frequency and resolution, complementary outputs with deadtime, hardware fade support, and interrupt-driven period callbacks.

Note

Features include up to 8 PWM channels using LEDC peripheral, configurable frequency and resolution per channel, support for complementary outputs with deadtime, hardware fade support, interrupt-driven period callbacks, and multiple timer groups for independent frequency control.

This implementation follows the lazy initialization pattern established in other ESP32 modules (EspAdc, EspGpio, etc.).
