Guangdong University of Technology-Electronic Information Association-Mini Standing Wave Suspension Device V2.0

Overview

Hardware chip:
DC-DC boost: MT3540
40kHz PWM generation: HK32F030
PWM driver: RZ7899
Colored lights: WS2812D
Serial port: CH340N (optional)
Phenomenon:
Two 40KHz ultrasonic Tr heads are placed in opposite positions to generate opposing ultrasonic waves. By controlling the distance between the two heads, standing waves can be generated. Place the foam on the wave node of the standing wave, and the foam will suspend.
Principle:
Complex, refer to the principle of ultrasonic suspension. - Zhihu (zhihu.com)--Comrade Zhao Yiming's explanation

Debugging points: Be sure to ensure the distance between the columns.
The installation instructions are as follows:

Attached is a demonstration video and the keil project of HK32.
The serial port and host computer have not been added yet. I hope that students with time can make up for this shortcoming.
