The LED Dot Matrix Control Technology Based on 51 MCU and CPLD

Abstract:

This paper describes a kind of LED dot matrix control technology based on STC89C51 MCU and complex programmable logic device CPLD, highlighting LED dot matrix display principle and the hardware and software implementation. This design has a flexible and programmable features, to ensure the stability of the system under the premise to achieve a variety of control programs on the LED dot matrix. According to this program,the breadboard adds external data memory, which can be used to extend the external bus, and this design has been successfully used MCU experiment.
