What are rows in the pixels architecture
In the Youtube video found on the Event-Based Concepts, it is mentioned that all pixels from the same rows are read simultaneously and their corresponding events will share the same timestamp. I have an EVK4 (IMX636) and the datasheet says the sensor
Establishing a time reference
Hello Prophesee Team, Is it possible to establish a time reference with the API (ideally Python)? For example, if one were to exploit the do_time_shifting functionality, could a timestamp simply be taken as the EventsIterator is called? Or is this too
Licensing T&C's for Kria embedded kit

x320 writes bad data to file?
With a x320 ES (which doesn't support the EVT3 format), a patched OpenEB (to support v4l2 devices) can only write raw files of collected data -- hdf5 files open then almost instantly close without any errors. If I convert the raw files to hdf5 with `metavision_file_to_hdf5`
Using the IMX636 + MIPI CSI-2 with Jetson Orin instead of AMD Kria
Does anyone have experience making this work? - Device tree looks like it's available here: https://github.com/prophesee-ai/linux-sensor-drivers - I'm curious if there's a driver available for the Jetson, and if not, if anybody has tips to write one for
