FSCONV (still very good, but deprecated)

FSCONV, the predecessor of lekseecon, connects the Level-D SDK to FSUIPC. It adds a lot of new Level-D 767 specific offsets to FSUIPC in the range 0x8B00 - 0x8BFF.

These offsets can be used by cockpit building software based on FSUIPC such as FSBUS, Phidgets, BU0836, and what have you ... as well for the Level-D 767 in FS2004 as in FSX.

FSCONV is in use since March 2005 and mature; development has concluded.

Clicking the computer icon to the right will give you the Software Installer (free!), User Manual included (1,9 Mb).

FSCONV is used for instance by It's Your Plane, look what they say about FSCONV:

IMPORTANT: From 1 May 2011, lekseecon can run in FSUIPC Mode. Each of the 805 lekseecon variables has a corresponding FSUIPC offset. There is no need to use FSCONV anymore...
