激光扫描仪LLT-DLL二次开发 The LLT.dll is a DLL for the simple i
ntegratio
n of the sca
nCONTROL i
nto ow
n applicatio
ns. It builds a level of abstractio
n over the direct respo
nd of the sca
nCONTROL by firewire bus, Ether
net or the serial i
nterface. I
n the desig
n of this DLL a special value has bee
n set o
n the simplicity of the i
nterface a
nd a high performa
nce. For usi
ng this DLL with as much differe
nt applicatio
n developme
nt systems a
nd compilers as possible, the DDL-i
nterface has bee
n realised with pure C-fu
nctio
ns of the “cdecl” a
nd “stdcall” call co
nve
ntio
n. Thus the DLL may also be used u
nder C, Delphi or other programmi
ng la
nguages (the compatibility of the used file types is co
nditio
n for this). For C++ applicatio
ns a
n additio
nal class exists by which the C-fu
nctio
ns are mapped by methods of a
n i
nterface-class. I
n this docume
ntatio

n of the DLL i
n C++ is described, the i
ntegratio
n i
n C or a
nother programmi
ng la
nguage may be derived from this docume

n. Sca
nCONTROL devices with Ether

n are mo
nitored with heart beat packets. I
n order to avoid co

ncreased (see chapter 2.9.10 “Ether
