| Abstract: | A LED dot matrix system controller model,based on FPGA device,which is implemented by using finite state machine,is designed.The primary control logic of the controller lies in the FPGA device.The I/O port of the controller can be directly connected with the interface of the drive board.And the data of the controller can be transmitted to PC monitoring center by using RS-485 or Ethernet bus.The simulation results and operation performance show that the controller is characterized by simple hardware,easy expansion and high reliability. |
