I was hoping to use this processor on the lepton 3.0. I think we should collaborate. If you see my previous posts on the topic, I think our needs are similar, although you are looking for considerably higher currents.
See my last posted thread here https://community.simplefoc.com/t/beginning-of-a-proposal-for-lepton-3-0/3115/19 on the general idea that I was aiming for.
Basically a general purpose motor driver based on the MCU you are talking about.
I think it is very important to realize that this stuff is not actually that easy. The internet is littered with at least a dozen half done projects and only one or two like VESC that are really done because people realize how much work it is after starting and then don’t continue. The Odrive guys realized how much work it was and decided they couldn’t figure out any other way to get paid except to go close source. The same thing happened with bl_heli.
You definitely need ST_link.
In line with how much work this stuff is, the first physical boards should probably be considered a draft. At least 3 iterations can be expected before it’s really solid even if the community collaborates.
