Introduction

This reference design demonstrates a DALI slave using Atmel® ATxmega32E5 microcontroller. A DALI master connected to the same bus can control the slave LED, either dimming or turning it on/off, to simulate control of a light bulb.

Ключевые особенности

  • Manchester Encoding and decoding with USART and XCL modules
  • EDMA (Enhanced Direct Memory Access) used for data transmission
  • Optocoupler isolation between DALI physical layer and the microcontroller
