3 STLUX
library
3.1 Introduction
The STLUX385A library is a collection of APIs aiming to simplify the usage of the STLUX
SMEDs and peripherals to application developers. Each collection of APIs is dedicated to
a specific device or functionality and named so “stlux_xxx” where “xxx” stands for the name
of the peripheral. The library is developed using the C language compatible with the IAR™
and Raisonance tools and is composed of the “stlux_xxx.c” and “stlux_xxx.h” relative files to
be included in your application.
