In this example `10000` is the period of the PWM waveform, some drive circuitry might require different values, it could also be altered in the event the drive frequency is audible/ In this example `10000` is the period of the PWM waveform, some drive circuitry might require different values, it could also be altered in the event the drive frequency is audible.
If your board uses a P-channel MOSFET to control backlight instead of a N-channel MOSFET, you may want to change `PWM_POLARITY_NORMAL` for `PWM_POLARITY_INVERTED`.
