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!


All released packages can be downloaded from https://www.kernel.org/pub/software/utils/i2c-tools/ (Mirror.) Files are signed by Jean Delvare.
