switch. It can switch two devices which each consume 300mA at 5V (or less).
This is good for fans, lights, or into relays for heftier stuff.
Here's what the usage looks like:
[root@penn sensors]# ls ltc1710-i2c-1-58/*
ltc1710-i2c-1-58/switch1
ltc1710-i2c-1-58/switch2
[root@penn sensors]# cat ltc1710-i2c-1-58/*
0
0
[root@penn sensors]# echo "1" > ltc1710-i2c-1-58/switch2
(blue LED turned on)
[root@penn sensors]# cat ltc1710-i2c-1-58/*
0
1
One problem with the device: It doesn't support reads. It ignores any
read transactions, so even detection with a read won't work. This
also means that the status of the switches has to be remembered and
can't be polled.
As simple as this device is, it is one of the few which actually
allows the computer to send signals OUT into the world to
control something.

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]):

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.

Nothing really special, but here is the simplest place to keep it, especially
as others may need it too.

* Better VDD internal computation, as described in the data sheet;
* Fixed the config file to reflect the above change;
* The library read the wrong file to get its gl518sm alarm data.

When computing the fan rotation speed, the register value of the dividers
was used, instead of the value it represents. I'ev fixed this ages ago
for the LM80 driver, but it seems I had forgotten to fix it at other places.

Read the intro; it describes how you can use CVS to diff between old releases.
Stupid copyright typo in piix4.c fixed

* (module) VIN limits are now set to sane values (3V instead of 30V, which
caused nasty overflows)
* (module) VIN limits had min/max swapped in gl518_attach_adapter
* (lib) TEMP_HYST used the VID sysctl instead of the TEMP sysctl, leading
to bogus readings
* (sensors) print n/a for gl518 not available readings.

Usage: isadump <ADDR-REG> <DATA-REG>
For the default LM78, this would be `isadump 0x295 0x296' (addresses may be
specified as decimal, octal or hexadecimal).

readings. (changed a u8 to a u16 in the data struct.) Now the temp
readings seem to work perfectly!

Please read the FAQ to see what is changed; there may be errors or omissions
yet. It is only meant for 2.x versions; the 1.x FAQ should not be deleted
from our homepage yet.

This could lead to memory corruption and to the could-not-unload-module
problem of earlier reports. With a little luck, this will resolve all
module loading/unloading problems reported.

* Force the Winbond into bank 0 before anything else is done
* Copied fan_div patch from lm78.c
* Copied IN_{FROM,TO}_REG patch from lm78.c
* Copied alarms computation bug fix from lm78.c
* Nicer way of managing banks: the bank number to access is now the high
byte of the (as u16 declared) register number. Only
w38781d_{read,write}_value needs now to be aware of banks. Also, the
w38781d_{read,write}_value functions now know that sensors 2 and temp, hyst
and over registers are word-sized.
* Introduced fan_div for FAN3 and 9-bit temperature readings.
* Made beep file work like the gl518sm one
* Corrected small VID problem (bit 4 was read from the wrong register)
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@121 7894878c-1315-0410-8ee3-d5d059ff63e0
* fan_div should now be handled correctly (please, could anybody play with
this? My fan is on FAN3, the one whose fan_div can't be changed...)
* IN_{TO,FROM}_REG no longer needs the additional in parameter, since we
eliminated scaling in the module.
git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@114 7894878c-1315-0410-8ee3-d5d059ff63e0
* sensors.conf.eg now contains LM80 declarations
* i2c/i2c-core.c again displays which adapters and clients are found and
connected, but it does not track the calls to transfer functions in dmesg
* Slight alarms computation bug in lm78.c repaired
* First hacks at lm80.c; expect a fully working version later today

This file consists of two numbers: the first is either 0 (global sound
alarm disable) or 1 (enable), the second is in the same encoding as the
'alarm' file and determines for which alarms the speaker will sound.
The new file was added to the module, the library and the sensors application.

Some basic support, in the form of sensors_get_all_features(), for chips that
are known to the library, but unknown to the application. prog/sensors has
a demo of how to use this, in function print_unknown_chip in chips.c.

An expression can now refer to the value it has to compute (@), but also to
other values. This is now perfectly valid as an expression:
vid + in_min - in_max * 2 / @
Not that this is very sensible, but you get the idea. Please install the
new example config file, or replace all old 'val' occurences with '@'.
