[sdiy] Chameleon Synth new path of Discussion

Oh, I see what you mean. Yeah, that's why I suggested we all
standardize on some sort of dev board and start building a set of libs
for it that we'd share. I think that could work well.

Sure, silicon makers have part libs but they are often hastily shown together for a mode of running that doesn’t always fit. Maybe you’ll use the RTOS they build for or will bare metal in the same way they writer envisioned. In all likelihood, this isn’t the case so you have to rework. Sure if you buy a Chameleon, it is developed, but if you are starting a new one, the supporting software is not an inconsiderable task.
