I posted a C++ class for controlling PICASO-SGC based devices on SourceForge. The class is currently only available via subversion (svn):

svn checkout svn://svn.code.sf.net/p/oledmanager/code/trunk oledmanager-code

At the moment the class is only tweaked for Linux based systems; if you need it to work on MSWin platforms (or WinCE) my contact details are in the source files. This is not a 4DSystems projects, so please direct any requests for support to the contact details in the source and not to 4D support.

The class was developed for an older version of the software specification but should work for current devices.
