APPLICATION NOTE
Atmel AT01244: DALI Slave Reference Design
Atmel 8-bit Microcontrollers
Features
• Compliant with international standard IEC62386-101, 102, 207
• Reference firmware design includes application, service and drivers
• Reference hardware made of three main parts:
• DALI interface, which bridges the voltage between DALI bus and microcontroller
• Microcontroller, which communicates with DALI master and controls the LEDs
• LED driver, which drives the LED controlled by microcontroller
Description
DALI (Digital Addressable Lighting Interface) is an international standard created for
lighting control and now becomes one of the more popular lighting interfaces today.
DALI protocol is a digital communication interface with master-slave structure, aiming
as a control gear between power supply and LED.
DALI slave communicates with DALI master based on half duplex signal with baud
rate of 1200 bit/s. Frame is defined as the sequence of bits used to transmit data.
Forward frame is from master to slave and backward from slave to master. The
definition of bit and frame can be found in IEC62386-102.

For this reference design, the hardware design files (schematic, BoM and PCB
gerber) and software source code can be downloaded from Atmel website. The
provided hardware documentation can be used with not limitations to manufacture
the reference hardware solution for the design.
