Design of Electronic Advertising Board Based on AT89C51 MCU
Abstract: Series of AT89C51 microcontroller is powerful,it is convenient for you to transfer and store data and it usually applies to every aspects of people’s live, such as medical equipment, billboards at the airport, banks and other electrical equipments of public places. AT89C51 microcontroller Led dot-matrix-based signage system uses AT89C51 microcontroller as the main control module.it uses clock circuit and reset circuit as outer circuit of the clock to drive 8x8 dot-matrix LED displays.it is applied to LED display dynamic display scan and displays dot matrix characters and can be modified according to different contents. Experiments show that the design is feasible.
