Design and Application of LED Beam Display Based on LED Number Display Interface

摘要

This paper introduces a design actualizing LED beam display. The design directly used LED number display interface on single-chip microcomputer emulation experiment system (Dais-958B+ teaching instrument). The handy hardware design is to obtain font and bit interface line through LED number display socket, and connect the line to LED beam display. The paper presents the overall idea, schematic diagram of hardware circuit and source program of software design to realize the beam display function.
