| For the scarcity of LED display control systema light control system which has the function of simulation at the top and the function of control based on NIOSII soft-core embedded processor at the bottom is achieved.The system has simulation software running on the PC. It simulates the pattern and color of changing of LED lights with the technology of VC++. By laying the module of LED lights,choosing the pattern of changing of each light,editing the color of changing of lighting,putting several snapshots together into a scene,previewing the scene . It finally download the data of lights made to the control system at the bottom to run by SD card.The bottom of the system add the component for full-color lighting control that is developed by hard description language into the self-defined of embedded SOPC control system by the way of embedding the NIOSII II of strong computing ability into FPGA and the tools of Quartus II EDA. After the simulation,downloading and debugging of the hardware system, it can build a special NIOSII SDK and design the software in the environment of NIOSII IDE.It is very convenient for developing the system by the concept of SOPC and it is very easy for adding or deleting every components.Therefore, cutting and expanding of the system can finish in a short time. The component made by the hard description language makes the analysis of data for light control more quickly and it can display at least 256 kinds of color, and has the moving effort of full- color change with patterns of change such as stable,gradual changes gradual brightness,gradual darkness and flicker. The product has the short cycle,little risk and low cost of developing. So it has the stronger competitive capacity of market. |
