Title: driver for 1-wire bus
Post by: _if_ on January 02, 2011, 01:41:24 pm
Hi guys,

is there anybody out there who is able to write a functional driver for the 1-wire bus?
Please let me know how much that would take!

thanks a lot!

I'm not at the stage where I'll be contributing templates, but just curious which 1-wire setup you have?  I have a hobby-boards (http://www.hobby-boards.com/catalog/advanced_search_result.php?search_in_description=1&keywords=hub&x=0&y=0) serial setup logging weather to my old debian server (mostly just rddtool scripting with a console and web display) but porting to my LMCE setup is quite a ways down on my todo list.  Assuming it is just a single daisy-chain usb/serial connection, the 1-wire interface is pretty easy to query and log.

Hi,

I have the Link45i which is a pretty simple interface and I was able to read the values through owfs, but could not integrate it into LinuxMCE...

The Link45i is RS232.  I have the USB Version:

Which works with the linux according to:

http://home.comcast.net/~ncherry/ (http://home.comcast.net/~ncherry/) with driver from: ftp://ftp.dalsemi.com/pub/auto_id/public/libusblinux300.tar.gz (http://ftp://ftp.dalsemi.com/pub/auto_id/public/libusblinux300.tar.gz)

there is some other info here of a guy using the temp sensors: http://marc.merlins.org/perso/homeha/2009-12.html#1wire (http://marc.merlins.org/perso/homeha/2009-12.html#1wire)
