This is an FPGA-based "shaking music" 3D real-time attitude synchronization tool.

2020 New Engineering Alliance-Xilinx Summer School project.

Inctroduction

Project Description

  • This project is a 3D posture simulation project based on FPGA. It reads the posture data of the onboard gyroscope and uploads it to the remote server to display the 3D posture model. This is a real-time attitude transmission system, which can upload the attitude information (how to rotate, etc.) of the device (Sea-Board) networked via WiFi to a remote server for display. The display method is a real-time 3D model: a Six-sided cube cube (currently still a short version).

Deployment steps

  • The onboard gyroscope transmits the original gyroscope attitude data through the IIC and gyroscope drive module.

  • The driver module stores the original data in RAM after processing. Using RAM and QSPI modules, Esp32 can access the data in RAM through the QSPI interface.

  • Esp32 connects to AWS IoT and uploads the onboard gyroscope data to the IoT cloud.

  • Create a HTML web page to realize a 6-sided cube that can rotate around the central axis, and each side is distinguished by a number with a different color.

  • Use the IoT cloud Web API to transfer cloud data to other web services (web server in this project), which is used to present the cube 3D posture online simulation.

Project expand

  • On the HTML webpage displayed in real-time posture, the cube can be replaced with various 3D objects (such as steering wheels, cars, cartoon characters, tumblers, etc.).

  • By modifying the model on the webpage, or adding some interactions, you can simulate driving, play a tumbler, etc., realize many expansion functions, and exert great potential.

Change Log

v0.1.1

  • Modified the three-axis angular velocity data transmission relationship, and solved the problem that the on-board gyroscope is synchronized with the flip direction of the webpage cube.

  • Updated and improved the structure of the project system.

v0.1.2

  • The refresh rate has been updated and the sensitivity of the cube rotation has been optimized.
