STEVAL-ILM001V1
Plug-in hardware module for the STM8S-DISCOVERY
interface for DALI communication
Features
■ Level translation from DALI voltage levels (-6.5
to 22.5 V) to microcontroller levels (3.3 V / 5 V
logic)
■ Proper rise/fall times for the communication
■ Current consumption limit (2 mA max.)
■ Overvoltage protection for misconnection of
rated mains voltage to DALI DA connectors
■ RoHS compliant
Description
The STEVAL-ILM001V1 is a plug-in module for
the STM8S-DISCOVERY kit and SW DALI library,
to create a fully working DALI slave application.
The STM8S-DISCOVERY + STEVAL-ILM001V1
work as a DALI slave device and can be
connected to and controlled by any DALI network.
The LD1 on the STM8S-DISCOVERY kit is used
as a light source. Its brightness, fade-in/out times,
etc., as defined by the DALI standard, can be
controlled through DALI to simulate a normal
lamp behavior.
The DALI (Digital Addressable Lighting Interface)
standard is a communication protocol widely used
in intelligent lighting applications. Its use is not
limited to fluorescent tube lamp dimmable
ballasts, for which it was initially designed, but
also for future LED applications.
The user is expected to be familiar with the DALI
standard and its details.
