ABSTRACT
This topic is based on the 8*8 LED dot matrix, design of 16*16 LED dot matrix display, by control the MCU and drive circuit of LED, to enable it to achieve better characters and simple graphical display effect.
This thesis describes structural characteristics, power and control display characteristics of LED dot matrix , besides this thesis also introduced the connect of local circuit, on the basis of know the details about the hardware , through the analysis of the functional modules of the system, in order to achieve the programming the LED dot matrix display control based on the MCU system .
At the end of this thesis,there are the design of the simulation results and the programming procedures, even given the issues which need to be improved in the design of electronic circuits in the LED production
Key Words: MCU; LED dot matrix; drive circuit of LED
