激光扫描仪LLT-DLL二次开发
The LLT.dll is a DLL for the simple integration of the scanCONTROL into own applications.
It builds a level of abstraction over the direct respond of the scanCONTROL by firewire bus,
Ethernet or the serial interface. In the design of this DLL a special value has been set on the
simplicity of the interface and a high performance.
For using this DLL with as much different application development systems and compilers as
possible, the DDL-interface has been realised with pure C-functions of the “cdecl” and
“stdcall” call convention. Thus the DLL may also be used under C, Delphi or other
programming languages (the compatibility of the used file types is condition for this). For
C++ applications an additional class exists by which the C-functions are mapped by methods
of an interface-class.
In this documentation only the integration of the DLL in C++ is described, the integration in
C or another programming language may be derived from this documentation.
ScanCONTROL devices with Ethernet connection are monitored with heart beat packets. In
order to avoid connection aborts during application debugging, the heart beat time out should
be increased (see chapter 2.9.10 “Ethernet Heartbeat timeout”).
