Key Settings of LED PWM Controller's API
.. note::
For an initial setup, it is recommended to configure for the timers first (by calling :cpp:func:`ledc_timer_config`), and then for the channels (by calling :cpp:func:`ledc_channel_config`). This ensures the PWM frequency is at the desired value since the appearance of the PWM signal from the IO pad.

LED PWM 控制器 API 的关键配置
.. note::
首次 LEDC 配置时，建议先配置定时器（调用函数 :cpp:func:`ledc_timer_config`），再配置通道（调用函数 :cpp:func:`ledc_channel_config`）。这样可以确保 IO 脚上的 PWM 信号自有输出开始其频率就是正确的。
