Thanks, I added your code to that wiki page.
I made a few changes which are now available at
https://community.elphel.com/files/393/20180118/
Raw image info is accessible in sysfs. Examples are in demo scripts:
a. /usr/bin/raw.py - demo for mmap
b. http://192.168.0.9/raw.php - demo for getting images via http requests
The scripts do not interrupt triggering - so images may not be in sync
(different frame numbers).
Also, note: if exposure ever gets longer than the trigger period the frame
numbers will get different.
More info about the scripts:
https://wiki.elphel.com/wiki/Working_with_raw_image_data#Capturing_and_downloading
So, do you transfer raw images over network?
I can add a small header to the data streamed by raw.php.
Best regards,
Oleg Dzhimiev
