基于fpga的点阵单向滚动显示程序文件

1、.基于 FPGA的 8*8 点阵显示器设计基于 FPGA的 88 点阵显示器（88 点阵显示器选用的是列共阴显示器）FPGA与硬件连接时通过驱动电路实现汉字显示。以下为软件部分；通过逐列扫描来显示汉字。现实的为“ 08 电气 2”的字样。拓展功能为向左滚动由开关控制滚动红字为字库部分，控制所要显示的是什么汉字蓝字为分频模块，控制扫描频率与滚动速度绿字为逐列扫描模块，library ieee;use ieee.std_logic_1164.all;use ieee.std_logic_unsigned.all;use ieee.std_logic_arith.all;entity dian is
