Design and implementation of LED matrix system controller based on FPGA
摘要
Abstract
In order to meet the requirements of LED matrix controller in the different occasions and ac-complish adjust different parameters properly,this paper introduces an implement of LED Matrix sys-tem controller based on FPGA through finite state machine.The primary control logic of the control-ler is integrated into FPGA device,which is composed of Serial Communication Module,Dual-port RAM Modules,LED Matrix Modules and Clock Generator Modules.Dual-port RAM Modules is cus-tomized by LPM.The other modules are described by Verilog HDL.The controller and the drive board are connected by the 08 port.The controller and PC monitoring center can communicate with each other through RS-232 serial bus.The simulation results on the Quartus II platform and operation performance showed that the controller possess the characteristics of hardware simplicity,expansion easy and high reliability.关键词
