It sounds like the answer to “can I run this application on RISC-V” is very dependent on what the backend for that application is. What’s the backend stack for your websites? Are they static HTML sites, or do they have other components? Someone else mentioned that they built postgres and mariadb Docker images for RISC-V, but I don’t even know which programming languages can be compiled for RISC-V right now.
A homemade RISC-V fightstick? This is combining all of my favorite things! I bought a leverless controller recently (an SGF Bridget).
I’m only vaguely familiar with microcontrollers, but I know there are libraries out there for using an Arduino to make a mechanical keyboard or fightstick. Is there something similar for the CH32V305?
