This is a very basic Rust no_std crate for reading from and writing to a memory-mapped (MMIO) SiFive Universal Asynchronous Receiver/Transmitter (UART) at the bare-metal level. It is used by the Diosix project for serial port communication. It is compatible with these SiFive system-on-chips:
- FU740-C000 (used in the HiFive Unmatched)
- FU540-C000 (used in the HiFive Unleashed)
- FE310-G002 (used in the HiFive1)
