I am trying to create a more-or-less standard documentation format for doc/chips/* files. I am not quite satisfied with the lm75 and lm78 docs yet, but it is starting to come. Basically, I want as much information in it as possible, and to generate most of it automatically. But that is harder than I though it would be. Also, a small library bugfix (class problem) and a doc-features fix. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@210 7894878c-1315-0410-8ee3-d5d059ff63e0

Kernel driver `lm75.o'
|
|
|
|
Prefixes: lm75 (LM75, I2C)
|
|
|
|
This driver implements support for the National Semiconductor LM75, a
|
|
`Digital Temperature Sensor and Thermal Watchdog with Two-Wire Interface'.
|
|
|
|
The LM75 implements one temperature sensor. Limits can be set through the
|
|
Overtemperature Shutdown register and Hysteris register. Each value can be
|
|
set and read to half-degree accuracy.
|
|
An alarm is issued (usually to a connected LM78) when the temperature
|
|
gets higher then the Overtemperature Shutdown value; it stays on until
|
|
the temperature falls below the Hysteris value.
|
|
All temperatures are in degrees Celcius.
|
|
|
|
The LM75 only updates its values each 1.5 seconds; reading it more often
|
|
will do no harm, but will return 'old' values.
|
|
|
|
|
|
/proc and sysctl interface files:
|
|
* temp (LM75_SYSCTL_TEMP)
|
|
Overtemperature Shutdown Value (RW,1), Hysteris Value (RW,1) and Current
|
|
Temperature (R,1).
