Hi,

I have managed to get an old Chronocam Gen1 QVGA-EM EVK. Is there a way to work with it using jAER? Prophesee has abandoned development for this camera, but its a great improvement over my old DVS.

Thank you in advance

At one time there was some work to try to interface it in CapoCaccia
(abandoned now, but maybe in sourceforge), but sans spec for USB and
bias control it will be impossible to integrate it. Do you have source
code for interfacing it, and some spec of the interface?

The other way is to use jAER as back end via UDP transport of the data
from the prophesee software. That's how we interfaced Gen1 Samsung DVS
to jaer.

Hi,

Thank you for your answer.

Specs are listed in Posch et al. [1] and there is some old software (both Windows and GNU/Linux) to play and record datasets. Maybe checking out the GNU/Linux code something could be done but never done it myself so not sure where to start.

Where is the software?

The paper specs are just a listing of #pixels, etc. What I meant by
specs are detailed specifications of the control of the FPGA or CPLD
that interfaces between ATIS and PC, what are the USB control transfer
commands, what is the data format packed into the bulk FIFOs, etc. It's
complicated.

I found the deleted AEChip class for the ATIS

$ git config --add diff.renamelimit 10000

$ git log --diff-filter=D --summary | grep delete |grep ATIS

See https://gist.github.com/joakin/67f5afdd083ccfb8fecd to recover this file to take a look at it. I don't remember how we did it.
