I2C Tools

I²C Tools for Linux

The I²C tools that used to be part of the lm-sensors package have been split to a separate package. The rationale for that move is that not all hardware monitoring chips are I²C devices, and not all I²C devices are hardware monitoring chips, so having everything in a single package was confusing and impractical.

The i2c-tools package contains a heterogeneous set of I²C tools for Linux: a bus probing tool, a chip dumper, register-level SMBus access helpers, EEPROM decoding scripts, EEPROM programming tools, and a python module for SMBus access. All versions of Linux are supported, as long as I²C support is included in the kernel.

I²C Tools 4 is coming, see the plan!
