This paper describes the proposal, design, and implementation of a novel WDMX controller which can provide versatile light effects with the increased capability of the mobility and the number of universes for LED lights. Both the algorithm for DMX protocol and how to implement the frame based on a 8bit micro-controller are explained. The conversion algorithm between the DMX frame and wireless LAN 802. 11b protocol stack is introduced and implemented. In final, some experiments are made to verily the interoperability of the developed WDMX controller with a commercial product of LED lights. 최대 9,999 staves with 30 refresh rate per second may have capability to show various light effects.
