So I’ve looked at this, and it’s a problem only with the header files used in the Seeed board support vs. the Arduino SAMD board support ☹ I tested on the Xiao and I get your error, I tested on the MKR1000 and I get no error.  
Basically, Arduino defines PinStatus as an enum type, while Seeed does not define this type.  
Its a big pain because this isn’t even MCU type-specific, but rather board-vendor specific - here we have two boards based on SAMD21 where one works and one does not…

If you want a quick fix, it is enough to add a  
`#define PinStatus int`  
to the top of the src/communications/StepDirListener.h file.

I will try to find a good solution for the next release of our library.
