Precise Timing Synchronization between PWM and Serial Read


I have two global shutter cameras which are triggered via external line, I also have an IMU.

I want to have the global shutter cameras run at 60hz and the IMU read at 480 hz and I want to have them synchronized.

Is this possible using only Jetson Nano hardware or do I need to use an external microcontroller?

hello lowellm,

there’s software approach by check their timestamps.
please refer to Argus sample, for example, argus/public/samples/syncStereo
you should obtain the sensor timestamps, and please have comparison of IMU timestamp to have them synchronized.
