Good Day

We use a "Debebola" debug board.

We added functionality - control of the brightness of the connected LED (using the PWM with one of the chip outputs).

Please, tell me, is it possible to add the properties pin "lighting brightness control" in the menu of standard pins of the media player settings? Or something others?

Many Thanks.

Processing Unit Descriptor

there are many slide bar you can use, pick one that not used to control led brightness.

Yes, but is not right method...

[VlKh_2251656]

It's not a native right method...

Hi,

The correct way of adding control to UVC device is to make use of extension unit descriptor.

Please check AN75779 app note to know how to use it.

Please, tell me, which paragraph in document?

Hi,

Not in document. You have to see the descriptors and the handling of extension unit event call in the source firmware.
