5.2.8‘C’ Programming 5.2.8.1 SM-PT100 Library

The SM-PT100 library of functions smartio.l provide a convenient way of accessing the SM-PT100 module.

All functions are written in ANSI C;

Prototypes are to be found in the file adclib.h.

Hardware Requirements

SMART I/O Base Module or Base Module and Extension unit;

SM-PT100 Module.

Software Requirements

The compiler from one of the following:

Ultra C Version 1.1.2 or higher;

FasTrak version 2.0.2 or higher.

The leftmost SM-Module has number 0 assigned to it a far as programming is concerned although physically this is slot 1!

Before a library function can be used, the function SMADCInit must first be called. This allocates the requested resources. Furthermore, this function needs to be called for each SM-PT100 module called within the task. Upon completion of the application, the function SMADCDeinit needs to be called for each SM-PT100 module that has been initialized.

In order to illustrate the use of the SM-PT100 library, an application example called demoadc.c can be found in the SMART I/O application directory (normally found in /<device>/APPLIC/SMART/CMDS).
