Hello!
Jan this is very good news. Can you in your spare time create an image
of your adapter that is talking to the i2c adapter (DS2482)?


I examined the documentation for using i2c functions under Linux and
it seems to me that to build an adapter such as yours was an
interesting concept but before I find myself making mistakes regarding
one. The term "home-brewn ELV type parallel-i2c adaptor" rings a loud
Control-G sound some place but I can't figure out where from.
