5.3.8 ‘C’ Programming

5.3.8.1 SM-THERM Library

The SM-THERM library of functions smartio.l provide a convenient way of

accessing the SM-THERM 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-THERM 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-THERM module called within the task. Upon

completion of the application, the function SMADCDeInit needs to be called

for each SM-THERM module that has been initialized.

In order to illustrate the use of the SM-THERM library, an application

example called demoadc.c can be found in the SMART I/O application

directory (normally found in /<device>/APPLIC/SMART/CMDS).
