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
).
