| Abstract: | The 16×16 light emitting diode(LED) dot-matrix dynamic display system based on AT89C51 MCU was designed,and the principle of LED dot-matrix dynamic display and the method of picking up Chinese character model were presented.The row driver circuit and the column driver circuit were designed by using Proteus software,and main program and display driver program were designed by using Keil software.Finally,the LED dot-matrix dynamic display system was simulated by Proteus software.The simulation results indicate that the system can reduce the development cost and improve the efficiency,and obtain the favorable display effects. |
