Can the universal motor control lab be used both for a sensored as wells as sensorless motor application.

Yes, take a look at the "Supporting Algorithms, Functions, and Motors Matrix" table in the User's Guide: https://www.ti.com/lit/pdf/spruj26

You'll see that it supports both FAST or eSMO sensorless configurations and QEP or Hall sensored configurations.

Are there any restrictions on the MCU supported in the lab, in my case F2837x vs F2838x.

I don't see any reason why you wouldn't be able to port it. There may be some minor changes to peripherals between F28002x and F2837x/F2838x that you may need to adjust for in the code, but the core functionality should be fine. And of course, you may need to make some changes related to pin assignments in the HAL files as well.

I think we discussed on another thread that the FAST library (if you choose to use it instead of a sensored option or eSMO) wasn't built for FPU64, so you'll need to turn that off for F2838x.

Thanks Whitney!

As you mentioned the library supports a Hall sensor feedback but does the library support a digital Encoder feedback also.

The QEP option I mentioned is for incremental encoder feedback. Is that what you're looking for is did you have some absolute encoder in mind?
