xavier pwm control

how can I write interface to write pwm from xavier pins?

all the tutorials talk about connect the jetson TX1/2 to arduino and then use the arduino pwm but the xavier has already pwm pins.

so where is the interface to write pwm??

I want to use c++ to control servo motor

Some old thread but I think the interface should still work.

Please note that the you should make sure the pin you want to use is already configured as pwm pin in our pinmux.

can you explain please?

Please download the pinmux spreadsheet from the download center. Make sure the pin you want to use is configured as PWM pin.
