Design of LED large screen display control system based on FPGA
Abstract Involved in this design is the LED dot matrix display. It has been widely used in today's society, used in the design is a specification for 16x16 dot matrix display, there have many small diodes in its interior , through the control corresponding to the light emitting diode which can make display designers need: Chinese characters, letters and so on. According to it glow effect, low cost, no power consumption advantages, its applications has become very widely, can be said to every corner of every city has its shadow. With the rapid development of society, designers gradually palm grip the how to design and control the content of the work, to improve the controllability of its .
This design topic is based on FPGA LED large screen display control system design. In the following, first introduced is led to the development of history, status and its internal structure and display principle. Secondly, based on FPGA were described in detail introduced, including FPGA design flow and method of use. Then puts forward the detailed design ideas: first of the overall circuit module pision, again how to make Chinese characters display in the LED lattice screen, how to make the design of seven words scrolling display. Finally tells the story of Verilog language writing and circuit diagram of compilation and simulation waveform.
