MXY8000-9 LED Display Comprehensive Experimental Instrument

Brief introduction

With the continuous progress of society and the rapid development of the semiconductor industry, LED, as one of the products, has quickly appeared on the streets and alleys: household energy-saving lamps, LED TVs, small shop commercial billboards, shopping mall large screen displays, and so on, with various new products emerging one after another. This instrument involves various applications of LED: static display, dynamic display, monochrome display, dual color display, three primary color principle, LED dot matrix, LED billboard, LED lamp demonstration audio decoding. Through this product, students can enhance their hands-on ability and design LED dot matrix screens of any length from a single unit board based on their understanding of the principles. To lay a solid foundation for students who want to work in the LED design industry to enter society.

2、 Teaching objectives

1. Master the principles of LED static display and dynamic display, compare their respective advantages and disadvantages, and design circuits according to actual needs;

2. Master the principle of RGB LED display and adjust various colors (256 × 256 × 256) according to the RGB color chart;

3. Master the principle of LED dot matrix display, so that students can use microcontrollers to control the LED dot matrix display of Chinese characters and simple images;

4. On the basis of mastering the principle of LED display control, one can use unit boards to assemble display screens of any size and control them through a microcontroller;

5. LED Fun Application: LED lights display the frequency of music;

6. Edit display content using specialized software and display it on LED advertising screens;

3、 Instrument functions

1. A digital tube static display experiment;

2. Four in one digital tube dynamic scanning experiment;

3. RGB three color LED color matching experiment;

4. 8 * 8 blue LED dot matrix Chinese character and image display experiment;

5. LED light audio display experiment;

6. Red green dual color (32 * 64) LED advertising screen display content editing experiment;

4、 Expected effect

Through this teaching instrument, students can have a deeper understanding of display principles, color rendering principles, microcontroller C language programming, downloading, debugging, and LED unit board display principles, from intuitive understanding to rational mastery. If students master all the knowledge, they can independently design a monochrome LED monochrome display screen of any length. If you want to design dual color or further design full-color displays, you need to deepen your learning in C language and controllers.
