Interfacing GPIB Add-On Boards
by Shigeo Hayashi
This project uses XDS Modula-2 to interface GPIB Add-On Boards
1. Rewrite GpibAc.H to GpibAc.Def
You can do it with little difficulty. For a portion of the result, see the codes below.
2. Rewrite SubClass.H to SubClass.DEF and SubClass.MOD
The procedures therein are not of great importance.
3. Modify ApiGpib1.Lib
xlib /implib /useord ApiGpib1 ApiGpib1.DLL
This is necessary because MSVC .LIB files are in COFF format, whereas XDS uses OMF format.
National Instruments NI-488.2
Direct access to Gpib-32.DLL
1. Rewrite Gpib-32.H
Use the H2D utility to create h2d_Gpib_32.DEF using the project file below.
H2D (.h to .def) project file (gpib_32.h2d) !header <*.h> #define __stdcall !end
Type in command line: h2d =p Gpib_32.h2d to obtain h2d_gpib_32.DEF
2. Get the run-time control procedures and status variables
See an example below.
