This article mainly introduces "how to realize white-light communication between two single-chip computers". In daily operation, I believe that many people have doubts about how to realize white-light communication between two single-chip computers. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to realize white-light communication between two single-chip computers". Next, please follow the editor to study!

Realization of white light communication between two single-chip computers

White light communication is also called "visible light communication". Its working principle is to modulate the information to be transmitted to the driving current of LED lamps and lanterns, making the LED lamps and lanterns extremely high.

The frequency flashes. The visible light communication technology based on white light LED combines the advantages of both optical communication and wireless communication, and conforms to the white light LED device.

The development trend of the first generation of green solid-state lighting light source is a new communication technology with high speed, flexibility and more environmental protection.

The launch board, which has four buttons, sends one character each

After the key is pressed, the emitter emits characters through LED, and the LCD displays the emitted characters.

At the same time, the receiving board displays the received characters through the LED receiving tube, and displays them on the LCD.

The emitted characters can be modified within the program and need to be improved:

1. The launch distance is a little close, about 30 centimeters

2. Increase the validity check of reception

At this point, the study on "how to achieve white light communication between two single-chip computers" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
