A REVIEW: FPGA IMPLEMENTATION OF DALICONTROLLER

DALI (Digital Addressable Lighting Interface) is serial data protocol which describes digital communi-cation between controller and one or more lighting device. The controller can control each light by means of Man-chester coding that is nothing but bi –directional data exchange. But malls, hospitals have large number of lightning devices at that time it is difficult to handle all lighting devices because as number of lighting devices increase, the time required for bi –directional data ex-change also increases as well as cost of system which is used to handle such a large no. of lighting devices also increases. So, it is essential to have cost effective solution to handle large no. of devices with increasing speed. Therefore, FPGA implementation of DALI controller with Manchester coding and DALI TOOL (V0.1) soft-ware is proposed for DALI commissioning between con-troller and one or more lightingdevice.
