Open Source Projects and Contributions
Our Open Source Projects
Here are the open source projects maintained by HumpbackLab:
1. INAV
- Project Description: Flight controller firmware for inertial navigation and autonomous flight
- GitHub: https://github.com/HumpbackLab/inav
- Technology Stack: C, Embedded Systems
- Introduction: We develop and optimize our flight controller firmware based on INAV to provide stable control for lightweight aircraft models.
2. Let's Fly
- Project Description: An Android application for controlling RC devices using CRSF protocol
- GitHub: https://github.com/HumpbackLab/LetsFly
- Technology Stack: Kotlin, Android, USB Serial Communication
- Introduction: Provides intuitive joystick controls, gyroscope-based flight control, and configurable channel switches. Supports USB OTG connection to RC hardware, suitable for mobile devices as remote controllers.
3. AT32 WebISP
- Project Description: Web-based ISP tool for AT32 microcontrollers
- GitHub: https://github.com/HumpbackLab/AT32-WebISP
- Technology Stack: WebAssembly, JavaScript
- Introduction: A browser-based programming tool for AT32 chips that enables firmware flashing using serial ports.
4. morb
- Project Description: A lightweight in-process publish/subscribe library for Rust
- GitHub: https://github.com/HumpbackLab/morb
- Technology Stack: Rust, mio, eventfd, Linux
- Introduction: Provides named topics, a fixed-size ring buffer, and poll-based notifications for efficient in-process message distribution on Linux, inspired by PX4's uORB design.
5. pymsp
- Project Description: A Python library for handling MSP (MultiWii Serial Protocol) messages
- GitHub: https://github.com/HumpbackLab/pymsp
- Technology Stack: Python, MSP, Serial Protocol
- Introduction: Supports packing, unpacking, and streaming processing for both MSP v1 and MSP v2 messages, suitable for flight controller protocol debugging, data parsing, and ground-station tool development.
