Inquiry about Jetson AGX Orin GPIO Support for 60Hz Trigger

Hello,

I am developing a carrier board using Jetson AGX Orin SOM. As part of this project, I am integrating a stereo camera that requires synchronized frames of 60FPS.

In usual, we have used a PWM generator to generate 60 frames per second (FPS) to the camera as Trigger Pulse. However, in this particular setup, I have connected the Orin GPIO pin (B8/H55) directly to the camera to generate the trigger signal. Is this fine to proceed. Is it possible to take exact 60Hz trigger?

And also, I would like to know if all the GPIOs on the Jetson AGX Orin support a 60Hz trigger. Any insights, recommendations, or documentation references would be greatly appreciated.

Hello, and welcome to the forums. This topic belongs in the Jetson forums.

I have gone ahead and moved it over for you.

hello manikandan.b,

actually…
there’s software example to demonstrate synchronized capture.
you may download the MMAPI package, $ sudo apt install nvidia-l4t-jetson-multimedia-api
please refer to /usr/src/jetson_multimedia_api/argus/samples/syncStereo
