ST Software and Cortex M3

I've been looking around at other cortex m3 platforms and I was really pleased by the ST offerings. They have great DSP libraries (optimized and C) as well as a full suite of motor control. The motor control suite comes with an application generator which sets all the parameters including closed loop tuning parameters using a variety of configurations.

It seems that the era of self tuning of motors is upon us. When traditional methods were used to tune processors using step responses, load tuning was a big part of the work. I suspect it still is if you want to get 100% out of the motor and driver for a specific application. These tools should make it easier though, getting you into the center of the envelope with zero effort.

But still, why no loop tuning option in the tools? Likely it introduces too many dependencies like host target communication, real time data collection and recovery and many more.

Great work ST
