basically an expanded LM75. It can have an external temp probe (in addition to the internal one), customizable conversion rate (in # of times per second, depending on power consumption requirements), and actually has a device-id register for easier/more-certain detecting! The only strange property is the low-limit. The low-limit doesn't act as a Hystersis value like the LM75. I.e., if the temp falls below it, it triggers an alarm instead of clearing it. Strange, ey? This makes using the chip for a thermostat control (like for a fan) much harder. But it *could* be used to turn on a heater to prevent your computer from freezing. :') Here's what my output looks like (without a remote sensor. temp's are the same format as the LM75 [high-limit, low-limit, value]): [root@penn adm1021-i2c-0-18]# ls -l total 0 -r--r--r-- 1 root root 0 Jan 9 23:42 die_code -rw-r--r-- 1 root root 0 Jan 9 23:42 remote_temp -r--r--r-- 1 root root 0 Jan 9 23:42 status -rw-r--r-- 1 root root 0 Jan 9 23:42 temp [root@penn adm1021-i2c-0-18]# cat * 3 60 20 0 76 60 20 24 PS- all temp values in the ADM1021 (limits and readings) are signed (2's comp) bytes. So, all readings go from -128 to 127 C (actually, the docs say it can only reliable sense down to -65), and only in whole degree increments. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@153 7894878c-1315-0410-8ee3-d5d059ff63e0
