基于FPGA的LED的大屏显示控制系统的设计。在下文当中,首先介绍的是LED的发展现况和它的内部结构及显示原理,其次针对FPGA进行了详细的说明介绍,包括FPGA的设计流程和使用方法

摘要本文所涉及的是LED点阵显示有关知识,LED显示技术广泛应用于现在社会的各个角落,本设计用到的是一种规格为16x16的点阵显示屏,它的内部有很多小的二极管,通过控制对应的二极管发光从而能让显示屏显示出设计者所需要的内容,包括汉字、字母等等。由于它具备发光效果好,造价低,耗电低等一系列优点,它的应用场合也因此变得非常广泛,可以说每个城市的每个角落都有它的身影。随着社会的快速发展,设计者渐渐的掌握了如何设计和控制它的工作内容,并且让它的可控性提高。41205
本次设计的课题是基于FPGA的LED的大屏显示控制系统的设计。在下文当中,首先介绍的是LED的发展现况和它的内部结构及显示原理,其次针对FPGA进行了详细的说明介绍,包括FPGA的设计流程和使用方法。接着就提出了本文的详细设计思路:首先对整体电路图进行模块划分,接着说明如何利用FPGA让汉字显示在LED点阵屏上,然后如何让所设计的七个字滚动显示。最后讲述Verilog语言的编写和对电路图的编译以及波形仿真。

 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.
