Re: [Owfs-developers] DS2484 support ?
I carefully diff-ed the DS2483 and DS2484 data sheets. There are no substantive differences. The DS2483 seems to be a little fussier about having Strong Pull-up (SPU) stopped before a reset. Thus, I would have expected the DS2484 to work fine. Can you check your hardware setup?

Interesting. So the only thing different here is the level translation goes down to 1.8V vs. 3.3V compared to the DS2483?
