2.2.11 LED Control (LEDC)

Introduction
The LED control (LEDC) peripheral is primarily designed to control the intensity of LEDs, although it can also be
used to generate PWM signals for other purposes. It has 8 channels which can generate independent waveforms that
can be used, for example, to drive RGB LED devices.
The PWM controller can automatically increase or decrease the duty cycle gradually, allowing for fades without any
processor interference.
