I2C Tools

I2C Tools is a cool project that brings together a bunch of handy tools for Linux. You get everything from bus probing tools to chip dumpers, and even some scripts for decoding EEPROMs. It's like having a toolbox just for I2C tasks!

What’s Inside the Package?

The tools are organized into categories, and each one has its own spot:

• eeprom: This section includes Perl scripts that help decode different types of EEPROMs like SPD and EDID. These scripts work with the “eeprom” kernel driver, which is already set up by default.


• eepromer: Here you’ll find tools designed for writing to EEPROMs. They depend on the “i2c-dev” kernel driver, but keep in mind, they aren't installed automatically.


• include: This part has C/C++ header files that let you access I2C and SMBus over i2c-dev. Good news—they come pre-installed!


• py-smbus: If you're into Python, this wrapper helps with SMBus access over i2c-dev. Just a heads-up: it doesn’t come installed by default.


• tools: This section features detection tools for I2C devices and register dumping. Just like the include files, these are installed right away.

Getting Started

You don’t need any special configuration script here! To build the tools, just run make, and then use make install to set them up on your system. Want to remove them later? No problem! Simply run make uninstall.

Your files will typically go into /usr/local by default. However, if you want to change that location, just edit the Makefile and adjust the prefix setting to whatever works for you.

Tweaking Your Build

If you're looking to save some space on your system, consider running make strip before installing—this makes smaller binaries! Just remember that doing this will make debugging harder down the line.
