README.TXT Driver File Contents (UPD303D1.EXE)

This disk contains all source and dll's to communicate with Dallas Semiconductor Buttons
Touch Memories under Windows NT and Win32s.  
This disk contains the Microsoft compatible code.  The contents of the disk are:
				1> MSWIN32S - example code implementing code that works under both NT and 
				   	      Win32s and communicates with Dallas Touch Memories.
				2> UTDAL16 - 16bit thunking dll for Win32s that communicates with sacwd300.dll.
				3> utdal32 - 32bit thunking dll for Win32s that communicates with utdal16, and 
					     calls the NT access system Touch Memory functions.
				4> SAUTHNT - source file to communicate with the Dallas Semiconductor NT access
					     system.

Your final application must be distributed with utdal32.dll utdal16.dll and the Dallas Semiconductor Windows NT 
installation disk.  The NT device driver must be installed for your apps to work under NT.  

Your applications should be linked with UTDAL32.lib inorder to communicate with the Touch Memories.  The file
mswindlg.h and mswindlg.cpp contain all Dallas function declarations and the required structure information.
Two Dallas functions have been removed from the interface.  Copy2RomData and CopyRomData are no longer availiable.
These functions are just repeats of the RomData function.  No functionality is lost.


All files are Microsoft compatible.
It is a requirement of Microsoft that you use a 32-bit compiler (Visual C++ 2.0) to
compile the 32-bit side of the thunking routines, and a 16-bit compiler
(Visual C++ 1.5) to compile the sixteen bit side of the thunking rountines.

    

Compile instructions:
        To write a win32s program to talk to Buttons:
                1. link with utdal32.lib 
                2. define all functions as they normally would be defined
                   see example file mswindlg.cpp
                3. all thunking applications must be statically compiled.
                4. provide sacwd300.dll, utdal16.dll and utdal32.dll with
                   your application.
          
        To compile the 16-bit thunking dll      
                1. nmake /fmakefile.16

        To compile the 32-bit thunking dll
                1. set environment variable to: CPU=i386
                2. nmake /fmakefile
