To start using the PWM Interface, you need to configure and activate the PWM port:
For each channel that you suppose to use:
Configure PWM frequency. The higher frequency, the smoother the output signal becomes. Read PWM Frequency [1].
Configure the duty cycle. The level of the output signal depends on the duty cycle value. Read PWM Duty Cycle [2].
Enable all channels that you suppose to use. All channels are equal, but every channel can have specific parameters (frequency and duty cycle). Read PWM Channels [3].
Enable the PWM port. When the PWM port is enabled, you can change configuration for each channel but you cannot activate or release channels.
