I implemented a bit of a STM32 and it was a chore and a half. I've noticed 2 things with the code base: 1. It's C but they really want C++. Qemu wrote their own class system, foreach loops, containers, etc. And because of that, when I tried to use actual cpp, compilation failed due to how many reserved keywords were used in headers and other mess. 2. As noted in other comments, copy paste and modify. It got me where I need to go. But it was a slog. Eventually I had gdb debugging my qemu build, and gdb debugging the program I was running. I could even connect in from the STM32 IDE which was nice
