drone-riscv is an experimental RISC-V platform crate for Drone, an embedded operating system. It provides support for the RV32IMAC Bumblebee Core architecture, targeting the riscv32imac-unknown-none-elf Rust target with the bumblebee riscvcore config flag. The crate serves as the foundation for building embedded applications on RISC-V microcontrollers using the Drone OS framework, enabling developers to leverage Drone's real-time operating system capabilities on RISC-V hardware. It integrates into projects through Cargo dependencies and is configured via features such as std. Documentation is available through the Drone Book and API references, and the crate is dual-licensed under Apache 2.0 and MIT licenses. It is actively maintained and intended for embedded systems development requiring RISC-V support.
