STM8L DALI slave interface
Introduction
This document describes the implementation of the Digital Addressable Lighting Interface
(DALI) in the STM8L 8-bit microcontroller family.
The DALI slave library for STM8L microcontrollers simplifies integration of the DALI slave
interface into customer applications. The implementation of DALI in STM8L, together with
the various STM8L features (peripherals, computation power, communication interfaces), is
mainly used in light control applications (example, electronic ballast control).
The STM8L DALI slave library was tested according to the DALI specification and comes
with a simple application example (DALI slave device), which was designed (and tested) for
use with the following evaluation boards:
• STM8L1526-EVAL
• DALI transceiver board (see UM1032: STEVAL-ILM001V1 hardware module)
The application example controls the light of the on-board LED diode. Light intensity is
controlled by the PWM method using a built-in timer. The external DALI master device must
control this application example (DALI slave device).
The DALI master devices were tested using the ST7DALI evaluation kit (master device
board and PC software).
