About `hifive1`

hifive1 is a board support crate for the SiFive HiFive1 and LoFive RISC-V development boards, providing low-level hardware abstractions and peripheral access for embedded Rust development. It supports multiple board variants including HiFive1 RevB, SparkFun Red-V RedBoard, and LoFive revisions. The crate is implemented primarily in Rust (92.3%) with assembly (5.7%) and shell scripts (2.0%), and requires a minimum stable Rust version of 1.59.0. It is licensed under a permissive MIT-like license and is part of the RISC-V Rust ecosystem. Note: The repository was archived in September 2025 and is now read-only.
