Expand description
@brief LEDC set duty and hpoint value Only after calling ledc_update_duty will the duty update.
@note ledc_set_duty, ledc_set_duty_with_hpoint and ledc_update_duty are not thread-safe, do not call these functions to control one LEDC channel in different tasks at the same time. A thread-safe version of API is ledc_set_duty_and_update @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 (0 - LEDC_CHANNEL_MAX-1), select from ledc_channel_t @param duty Set the LEDC duty, the range of duty setting is [0, (2duty_resolution)] @param hpoint Set the LEDC hpoint value, the range is [0, (2duty_resolution)-1]
@return - ESP_OK Success - ESP_ERR_INVALID_ARG Parameter error
