Design of 16×16 Dynamic Scanning LED Dot Matrix Module for Single Chip Microcomputer
To achieve the display of static and scrolling characters,this paper designs a 16×16 monochrome dot matrix display module.4 pieces of 8×8 monochrome dot matrix modules are used to form a 16×16 dot matrix module,and Altium Designer is used for the overall design of the circuit schematic and printed circuit board.The control system is based on the 51 microcontroller minimum system,and the display program is written in the Keil C51 environment.The chips used are 74HC595 and 74HC138.The overall workload of this module design is relatively small,and the process of this design is beneficial for exercising practical hands-on ability and improving the ability to analyze and solve problems.
