I /think/ I have that working, but this driver has no docs describing its fault output. There are 2 empty pins on the connector but no info on the state of those pins, in or out of fault. So I may have to wire it up and find out. I haven't tried to google this driver to see if it has downloadable docs, yet. Next obviously.
