The point is, that the init sequence for the 600 also works for the 610 (ie.
uncompressed mode), BUT the sensor has a different interface (5bit...), so
the data received is synced, but (noisy) black. If yut point the cam to a
large contrasts, it is possible to see a week scheme...
If we find the correct register settings for the VV6410 sensor, we could
use the LegoCam at least in a (slower) uncompressed mode.
