Hi Karis,

Are you trying to use it as GPIO or PWM? If you choose to use as GPIO, then it can only be either pulled up or down. Not able to configure the brightness.

Hi WayneWWW,

I think, I use it as GPIO.
How do I use it as PWM? thanks!

You can choose the pin function in the spreadsheet.

Hi WayneWWW,

I follow Jetson Nano Developer Kit 40-Pin Expansion Header Configuration and the way from the links below.I set the period and duty cycle, but the monitor’s backlight is not different.
Which value should I set for period and duty cycle?
