Wired Communication Solutions for Lighting
Many lighting applications require some form of
communication for remote control but also for diagnostic
purposes. Some of the most common interfaces used in
lighting are:
■ 0-10V
■ DMX512
■ Digitally Addressable Lighting Interface (DALI)
0-10V Interface
All PIC microcontroller families offer models that integrate
an Analog-to-Digital converter peripheral with a minimum of
8-bit resolution that allows them to connect to the industry
standard 0-10V interface with minimum external component
count. Most Flash PIC microcontroller models offer a
10-bit resolution ADC, while 12-bit resolution is available
on selected models. Each I/O pin is protected by a pair of
(clipping) diodes so to prevent latch-up and damages that
could follow from the incorrect wiring of a 0-10V interface
(over-voltage).
There are different 0-10V specifications based on
the intended application. The 0-10V control interface
for controllable ballasts is defined in Annex E of the
IEC60929 specification. The 0-10V control interface for the
entertainment industry is defined by ANSI E1.3-2001.
Digitally Addressable Lighting Interface (DALI)
DMX512
The DMX512 interface (ANSI E1.11) has gained great
popularity in theatrical/entertainment lighting applications
because of its simplicity and low cost. It is based on a 250
Kbaud asynchronous serial interface that uses the standard
RS-485 differential line transceivers. Transmitter and
receivers can be implemented on most PIC microcontrollers
in a few lines of code. PIC microcontrollers that offer a
EUSART peripheral allow for the simplest and most efficient
implementation of the protocol.
Application note AN1076 offers an example implementation
of both a transmitter and typical DMX512 receiver on a
PIC18F2420 model.
The figure below shows an application example where
a PIC24FJ16GA002 implements a DMX512 receiver to
control three PWM output channels (each capable of 16-bit
resolution).

implementation of a bridge between DALI and a standard
RS-232 serial interface.
DALI Ballast Software Library
A DALI ballast software library is available for PIC MCUs
that comply with the latest release of the IEC60929
specification. Contact your local sales office for availability.
