Description of STLUX385A peripheral library Introduction This user manual provides complete information for SW developers on the STLUX385A library, a library of APIs useful to get familiar developing applications for the STLUX385A digital controller and its peripherals. The STLUX385A is an STMicroelectronics® digital device tailored for lighting applications. The heart of the STLUX is the SMED (“State Machine Event Driven”) technology which allows the device to operate several independently configurable PWM clocks with up to 1.3 ns resolution. A SMED is a powerful autonomous state machine which is programmed to react to both external and internal events and may evolve without any software intervention. The tools provided by this Kit will help you understand the SMEDs and how to program them in your applications. SMEDs are configured and programmed via the STLUX internal low-power microcontroller (STM8). This manual describes the tools provided in this kit.
