文档介绍：编号淮安信息职业技术学院毕业论文题目基于 FPGA 的 LED 点阵设计学生姓名王飞学号 12012117 院系电子工程系专业物联网应用技术班级 115121 指导教师许金星顾问教师杨永二〇一五年六月摘要 I 摘要主要研究基于 VHDL 的 Led 点阵汉字滚动显示。首先描述了基于现场可编程门阵( FPGA )的硬件电路,以及点阵显示汉字的原理;然后在单个 16X16 LED 发光二极管点阵上滚动汉字的原理;最后给出了描述其功能的 VHDL 语言程序设计方法。通过编程、调试、仿真、下载正确地实现了汉字滚动显示扫描结果, 其硬件系统的实验验证也获得了与软件模拟仿真结论相吻合的结果。关键词: LED 点阵; FPGA ; VHDL 语言;汉字滚动显示 Abstract II Abstract Primary research is based on FPGA, Led Scrolling dot matrix characters. First described based on field programmable gate array (FPGA) hardware circuit, as well as the principle character dot matrix display; and then ina single 16X16 LED scrolling LED dot matrix on the principles of Chinese characters; Finally, the VHDL description language program of its functions design. Through programming, debugging, simulation, download the correct character scroll achieved scan results, the experimental verification of its hardware and software are also obtained findings consistent with simulation results. Keywords : LED dot marix; FPGA; VHDL language; Chinese character scrolling display. 目录 III 目录摘要.................................................................................................................................
