Design Of LED Lights Control System Based On NIOS Soft-core

For the scarcity of LED lights control system, a light control system which has the function of simulation at the top and the function of control based on NIOS 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 OpenGL embedded in 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 control made to the control system at the bottom to run.The bottom of the system add the IP core 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 NIOSⅡof strong computing ability into FPGA and the tools of QuartusⅡEDA. After the simulation,downloading and debugging of the hardware system, it can build a special NIOS SDK and design the software in the environment of NIOS IDE. It controls the reading and playing of data for lights control by the way of multi-task control of theμC/OS embedded real time operation system. And at last the IP core of light control controls the full-color show of LED lights using PWM ports.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 IP core 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 5 patterns of change such as stable,gradual change,gradual brightness,gradual darkness and flicker. The product has the short cycle,...
