Study and Realization of Stage Lighting Console

At present, most of the stage lighting console designs are based on MCU(Micro Control Unit), but its technique advances, information storage and real-time performances are deficient. This paper proposed that using the technique of ARM-Linux can realize the function of lighting console. This technique adopted S3C2440 processor as the main control chip of the hardware. The transmission of dimming data followed the DMX512 agreements. The low-level driver programs were developed under linux2.6.12, it provided interfaces for upper layer application. Testing results show that this system has perfect dimming performance and scalability, which is easy to upgrade. Our design has important theoretical significance and practical value for stage lighting control.
