Tool/software:

There are many FAST libs in MotorControl SDK 5.03. What is the difference, and when should I use each?

    Hi,

    I'm not able to find where we document this. We may need to add a readme file into the SDK for this, I'll look into getting this added.

    For now please reference the below table. The feature set and supported motors are different which affects the memory footprint. COFF & EABI files are for different compiler versions.

    Best,

    Kevin

    Thank Kevin!

    On the one hand, under "fast_full_lib," is written "Compatible with ROM," while on the other hand, any C2000 with FPU is written.

    So, can the same library support both? Or ROM FAST (supporting devices only) or FLASH (for any C2000 with FPU)?

    Hi,

    fast_full_lib can support both ROM and FLASH / software library cases. Not all C2000 devices have FAST stored in ROM however. So if a device has FAST in ROM (xC de-notion in part #) then less variables / code will be needed in software / FLASH memory.

    Best,
