摘要
主要研究基于VHDL语言和FPGA的LED点阵汉字滚动显示器的设计。在介绍16×16LED点阵块工作原理的基础上,给出了基于FPGA的系统硬件电路,以及LED点阵实现汉字滚动的设计方法,并在QuartusⅡ软件集成开发环境下对整个系统的软件进行了仿真测试,实验仿真及硬件测试结果表明设计完全满足要求。该设计具有较为重要的应用价值。
The design of LED dot matrix Chinese character scrolling based on the VHDL language and the FPGA are studied. The working principle of the 16× 16LED lattice block is introduced, and the hardware circuit based on FPGA and the LED lattice realization method of Chinese characters scrolling are given. Then the software of whole system is tested under Quartus II software integrated development environment. The simulation and hardware test results show that the design completely meets the requirements and has important application value .
