Flask backend development interface example, using Flask
...Authentication examples include JWT, mobile verification codes, and WeChat-based login scenarios. Reporting modules generate Excel, Word, PDF, and hierarchical tree outputs. Celery, APScheduler, unit tests, coverage reports, Docker, Gunicorn, Nginx, and Drone CI demonstrate supporting infrastructure around the API. The repository is organized as a collection of real backend patterns rather than a single narrowly focused service.
Airborne avionics platform for drone system identification and control
...This UAV drone hardware senses critical orientation parameters through a MPU-9250 9 Degree of Freedom sensor. This sensor measures 3-axis Acceleration Nx, Ny, & Nz, Compass Mx, My, Mz, and Gyroscopic rate P, Q, & R. A sensor fusion and numeric integration algorithm then combines these 9 parameters to 4 Euler parameters/Quaternions. An Euler body 1-2-3 sequence relates these to Roll/Pitch/Yaw. Air data is measured through altimeter and differential pressures. GPS measures position and track.
