Software Requirements

The compiler belonging to one of the following environments:

•Ultra C Version 1.1.2 or higher;

•FasTrak for Windows version 2.02 or higher.

Attention: As far as programming is concerned, to the SM-Module on the very left the figure ’0’ is assigned, although physically it is slot 1.

Before a library function can be used, the function SMACI1Init must be called first. By this the requested resources are allo- cated. Beyond, this function needs to be called for each SM- ACI1 Module called within the task. Upon completion of the application, the function SMACI1DeInit needs to be called for each SM-ACI1 Module that has been initialized.

In order to illustrate the use of the SM-ACI1 library, an applica- tion facsimile called demoaci1.c can be found in the SMART I/ O application directory (normally to be found in /<device>/ APPLIC/SMART/SRC).
