Hi, I'm using the MKRIMU Shield, its all working fine but I'm just wondering what the point of the interrupt pin connected to D0 is?

It doesn't get used in the library, as I have removed its use and all still works fine, i'm assuming its for a future feature?

I need to use pin D0 for a second serial port and hence need to disable the IMU from stomping on the serial TX pin, can't find another way to route the TX pin elsewhere on my MKR-W1010 board.

There was a recent thread about using software serial on the MKR series.

Cannot put my finger on it right now but you could use the SEARCH option magnifying glass at the top right of the page.
