Hi, > Can anyone point me out on how to connect that device?
The DS1822 is a 1-wire slave, therefore you need a 1-wire bus master, e. g. the DS2480B, to establish bus communication. I did some tests with the DS2480B connected directly to the fox board: http://tech.groups.yahoo.com/group/foxboard/message/3512 If you do not like soldering yourself, you could use a USB to 1-wire adapter manufactured by ECLO: http://www.eclo.pt/eclo2/Portals/0/ds/10000500011a-en.pdf This adapter includes a FTDI USB to serial converter and the above mentioned serial to 1-wire converter DS2480B. The drivers should be included in Linux kernel version 2.4 and higher. If the adapter is not recognized correctly (i. e. connected to e. g. ttyUSBx), then follow the instructions here: http://owfs.sourceforge.net/adapters/patch.html There is also a USB to 1-wire adapter DS9490 manufactured by MAXIM, http://www.maxim-ic.com which is based on the DS2490 chip.
