I have got the DS1971 256-Bit EEPROM iButton today. While connected to the 1-Wire bus, the owfs shows following:
r...@ubuntu810:/usr/local/tridicka/1wire/uncached/14.AC5755040000# ls -l -r--r--r-- 1 root root 16 2010-08-17 11:37 address -r--r--r-- 1 root root 256 2010-08-17 11:37 alias -rw-rw-rw- 1 root root 8 2010-08-17 12:56 application -r--r--r-- 1 root root 2 2010-08-17 11:37 crc8 -r--r--r-- 1 root root 2 2010-08-17 11:37 family -r--r--r-- 1 root root 12 2010-08-17 11:37 id -r--r--r-- 1 root root 16 2010-08-17 11:37 locator -r--r--r-- 1 root root 1 2010-08-17 12:56 lock -rw-rw-rw- 1 root root 16 2010-08-17 11:37 memory -r--r--r-- 1 root root 16 2010-08-17 11:37 r_address -r--r--r-- 1 root root 12 2010-08-17 11:37 r_id -r--r--r-- 1 root root 16 2010-08-17 11:37 r_locator -r--r--r-- 1 root root 32 2010-08-17 11:37 type I just wonder, why is the memory file size 16-bytes only (see above). In the owfs It is possible to read/write 16 bytes from/to the "memory" file only. In the Maxim sheets <http://www.maxim-ic.com/datasheet/index.mvp/id/2823>the DS1971 is described as 256-bit and on the OWFS web <http://owfs.org/index.php?page=standard-devices> as a 32B device. Am I missing or overlooking something? Thanks for hints Petr Jakes
