Introduction
The Host Interface Library for the VT1433B is a set of functions that allows the
register-based VT1433B to be programed at a higher level than register reads and
writes. The library allows groups of VT1433Bs to be set up and programmed as
if they were one entity.
The VT1433B uses the same software as the VT1432A 16 Channel
51.2 kSamples/s Digitizer plus DSP.
Two version of the Host Interface Library are available. One is the HP-UX
C-Language Host Interface Library which uses SICL (the Standard Instrument
Interface Library) to communicate to the VT1433B hardware. The other is the
VXIplug&play Library which communicates with the hardware using the
VXIplug&play standard. This chapter covers the C-Language version. If using
the VXIplug&play version, this chapter will not be needed. Instead, see the
chapters titled “Getting Started With the VT1433B” and “Using the VT1433B”.
NOTE The C-Language Host Interface Library has been provided for the purpose of
backward compatibility and is no longer supported. New users should use the
VXIplug&play Library while older users are encouraged to migrate their applications
to the VXIplug&play library.
The library includes routines to set up and query parameters, start and stop
measurements, read and write data and control interrupts. Routines to aid
debugging and perform low-level I/O are also included.
For information on diagnostics see the chapter titled “Troubleshooting the
VT1433B.”
Almost all functions in this library return 0 if they complete successfully and a
negative error number if there is a problem. The return value of the function
should always be checked and appropriate action taken for non-zero values. See
the on-line man pages for more information on error messages.
