Expand description
@brief A thread-safe API to set and start LEDC fade function, with a limited time.
@note Call ledc_fade_func_install() once, before calling this function. @note For ESP32, hardware does not support any duty change while a fade operation is running in progress on that channel. Other duty operations will have to wait until the fade operation has finished.
@param speed_mode Select the LEDC channel group with specified speed mode. Note that not all targets support high speed mode. @param channel LEDC channel index (0 - LEDC_CHANNEL_MAX-1), select from ledc_channel_t @param target_duty Target duty of fading [0, (2**duty_resolution)] @param max_fade_time_ms The maximum time of the fading ( ms ). @param fade_mode choose blocking or non-blocking mode
@return - ESP_OK Success - ESP_ERR_INVALID_ARG Parameter error - ESP_ERR_INVALID_STATE Channel not initialized - ESP_FAIL Fade function init error
