How to create a new CIN block to call to Advantech 32-bit DLL Driver

CIN Overview:The LabVIEW Code Interface Node (CIN) supplies a way for user to link external code

written in a conventional programming language to LabVIEW. A CIN is a block diagram node associated with a section of source code written in a

conventional programming language. You may compile the source code first and link it to form executable code. LabVIEW calls the executable code when the node executes, passing input data from the block diagram to the executable code, and returning data from the executable code to the block diagram.

Steps for Creating a CIN code under Windows 951) Place the CIN block on a Block Diagram

2) Add Input and Output Terminals to the CIN. Press right mouse key and select “Add Parameter” for each raw (Left is the Input or Initial value, left is the Output)

3) Presses right mouse key and select Create .c File item and modify the code inside. Please take care of those codes,

/* * CIN source file */

/* Source CIN of adManager.llb\DeviceOpen.vi */#include <extcode.h>#include <hosttype.h>#include <windows.h>#include "driver.h"

/* stubs for advanced CIN functions */

typedef struct {LVBoolean Status;int32 Code;LStrHandle Source;} TDSTA;

CIN MgErr CINRun(uInt32 *DevNum, uInt32 *DevHandle, TDSTA *ErrInfo);

CIN MgErr CINRun(uInt32 *DevNum, uInt32 *DevHandle, TDSTA *ErrInfo){ int len; char msg[256], buf[100]; MgErr Err;

ErrInfo->Code = DRV_DeviceOpen(*DevNum, DevHandle); if(ErrInfo->Code) { ErrInfo->Status = LVTRUE;

/* Get Error Message */ StrCpy(msg, "DeviceOpen.vi : "); DRV_GetErrorMessage(ErrInfo->Code, buf); StrCat(msg, buf);

len = StrLen(msg)+1; if(Err=NumericArrayResize(uB, 1L, (UHandle *)&(ErrInfo->Source), len)) return Err; LStrLen(*(ErrInfo->Source)) = len; StrCpy(LStrBuf(*(ErrInfo->Source)), msg); } else { ErrInfo->Status = LVFALSE; } return noErr;}

4) Set up the compiler environment (under DOS Prompt Windows). Please run below line to set up the compiler environment. Here C:\VC5.0\DEVSTUDIO\VC\BIN\ is the directory of VC compiler.

@echo offCALL��C:\vc5.0\devstudio\vc\BIN\VCVARS32��x86

5) Compiler the source codes. Create a .LSB file, Devopen.LSB, to be linked to a CIN block in Labview environment latter.

Nmake��/f��Devopen.lvm > c.err

Below is the content of Devopen.lvm. Here the filename, Devopen.lvm, could be a user defined filename. If you want to use standard C or Windows 95 or Windows NT libraries, define the symbol cinLibraries in a .LVM. The file, ADSAPI32.LIB, is the header library of C:\WINDOWS\ADSAPI32.DLL.

12

IDE=VCname=Devopentype=CIN

cinLibraries=adsapi32.lib

!include $(CINTOOLSDIR)\NTLVSB.MAK

6) Reload Code Resource From …. Press right mouse key to show the POP-UP dialog box and select Reload Code Resource From ... item.

Please select a proper .LSB file from below dialog box.
