Description
|
|
-----------
|
|
|
|
The W83L785TS-S is a digital temperature sensor. It senses the
|
|
temperature of a single external diode. The high limit is
|
|
theoretically defined as 85 or 100 degrees C through a combination
|
|
of external resistors, so the user cannot change it. Values seen so
|
|
far suggest that the two possible limits are actually 95 and 110
|
|
degrees C. The datasheet is rather poor and obviously inaccurate
|
|
on several points including this one.
|
|
|
|
All temperature values are given in degrees Celsius. Resolution
|
|
is 1.0 degree. See the datasheet for details.
|
|
|
|
The w83l785ts driver will not update its values more frequently than
|
|
every other second; reading them more often will do no harm, but will
|
|
return 'old' values.
|
|
|
|
|
|
Known Issues
|
|
------------
|
|
|
|
On some systems (Asus), the BIOS is known to interfere with the driver
|
|
and cause read errors. The driver will retry a given number of times
|
|
(5 by default) and then give up, returning the old value (or 0 if
|
|
there is no old value). It seems to work well enough so that you should
|
|
not notice anything. Thanks to James Bolt for helping test this feature.
