Introduction

The Digital Addressable Lighting Interface (DALI) is an international standard that governs intelligent lighting control. DALI was developed to replace analog lighting control with a flexible digital control system. Microchip's Universal Asynchronous Receiver Transmitter (UART) module has added protocol support features that simplify DALI usage. This technical brief will give a short summary of the DALI protocol and explain how to use the UART module for DALI control.
