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. -- Gregg C Levine [EMAIL PROTECTED] "This signature was once found posting rude messages in English in the Moscow subway."
