debugmodule.h

Revision 384, 8.3 kB (checked in by pieterpalmers, 17 years ago)

- temporary commit as backup measure
- rewrote synchronisation code
- receive streaming based on SYT works
- transmit streaming synced to received stream sort of works, still

have to iron out some issues.

NOTE: all devices but the bebob's are disabled in this code,

because they still have to be ported to the new sync
mechanism.
