I²C, SMBus and hardware monitoring references

This document contains all kinds of useful references to I²C and SMBus documents and implementations, and to hardware sensors documentation and implementations. Please report any other references you have found!

I²C
- General overview
- I²C FAQ
- Philips, the I²C developers
  This site contains many example programs
- Simon Vogl's I²C Linux kernel module
- Simon's I²C newsgroup
SMBus
- SMBus specification documents
I²C and SMBus implementations
- Intel PIIX4 (82371AB)
  Intel SMBus adapter, integrated with many other functions. There are datasheet for most chipsets.
- VIA South Bridge (VT85C586B)
  VIA I²C adapter, integrated with many other functions. There is a separate section with datasheets.
- Acer Labs M1533/M1543C
  Acer Labs SMBus adapter, integrated with many other functions.
Hardware monitoring chips
- National Semiconductors
  LM75/78/79/80 reference sheets.
- Winbond
  W83781D, W83782D, W83783S and W83627HF chips. Data sheets can not be found online for the W83627HF chip.
- Analog Devices
  ADM1021 and ADM9240 reference sheets
- Linear Technologies
  LTC1710 data sheets
- Genesys Logic
  GL518SM and GL520SM data sheets
- Hewlett Packard
  HP Maxilife (datasheets only under NDA...)
- Silicon Integrated Systems Corp.
  SIS5595 data sheets
- Maxim
  MAX1617 data sheets
- Dallas
  DS1780 data sheets
Other protocol information
- IPMI documentation
  Intelligent Platform Management Interface, a standard for hardware monitor chip reading
Hardware Monitoring Applications using the lm_sensors package
- Procmeter
  A comprehensive system monitoring package. Nice desktop app. Recommended.
- A web-based hardware monitor
  This is created by Phil Edelbrock, one of our main project contributors
- wmlm78/wmsensors homepage
  wmlm78 and wmsensors are graphical extensions of lm_sensors, which can be docked in Window Manager.
- klm
  Brendon Humphrey's KDE display program for lm_sensors.
- GLS
  Stijn Jonker's program to make nice graphs of the lm_sensors output. Recommended. Requires mysql package.
Other Hardware monitoring implementations (not using lm_sensors)
- The official lm_sensors homepage
- Alexander Larsson's lm78 module
  This is the original module lm_sensors is based upon
- Ronald Schmidt's lm78 module
- Beowulf project lm78 module
  Written by Erik Hendriks. This Nasa site may have a newer version. There is also SCMS Cluster Management for Beowulf clusters available, which supports the LM78 through the above kernel module.
- txwd, another lm78 module
- András Major's LM75 module, and graphical monitor for it
Other useful tools
- CPUBURN
  CPU-heating program to stress-test marginally-cooled systems and test lm_sensors.
