STEVAL-ILL057V1: four independent high brightness LED
Ambrogio D’Adda
Introduction
The STEVAL-ILL057V1 demonstration board is a complete and configurable solution to
manage four independent high brightness LED channels using the STLUX385A digital
controller, which embeds advanced peripherals tailored to generate high resolution PWM
signals. The LED current is independently regulated by the fixed-off-time (FOT) principle on
each channel.
This document describes how to use the STEVAL-ILL057V1 board, the hardware and the
firmware implemented on the board as well as the relevant measurements. The
STLUX385A shipped with this board has already been programmed with firmware tailored
for the STEVAL-ILL057V1 application and the source code is available.
Figure 1 gives an overview of the demonstration board diagram.
