In the “old hardware projects” box, I had a HiFive1 board with SiFive FE310 RISC-V microcontroller, and Velleman’s Arduino based ALLBOT spider robot. Replacing Arduino with HiFive1 and rewriting ALLBOT’s C-based firmware from the ground up in Rust felt exciting! I knew that Rust targeted RISC-V, but it even had the support specifically for the HiFive1...
