You may have already done it but I imagine that one of the changes for the kinds of currents you are talking about would be switching to hall sensors for the current monitoring. One of the nice things about doing this is you can actually measure the phase currents rather than just the low side.

I've been playing with InstaSPIN on and off for a year or so now. I was using an EVM with the DRV8312 but it wasn't powerful enough for my needs and I blew it up in the end. I've recently started using the new Launchpad and BoosterPack and I really like them. I've also seen comments suggesting...

When you go to download Stellarisware you are told that the latest version supports LM3S only and that designs based on LM4F should migrate to Tivaware. As I understand it LM3S is Stellaris and LM4F is now Tiva (its the same chip as a TM4C something or other). You are right that Stellarisware...

I actually have all three ControlCARDs. 28068M is the newest and is the only one that includes InstaSPIN-FOC and InstaSPIN-MOTION. LM4F211 includes InstaSPIN-BLDC but I get the feeling that TI would prefer everyone to move to -FOC. LM4F211 for motor control seems to be a bit of a deadend at the...
