I2C TOOLS FOR LINUX

This package contains an heterogeneous set of I2C tools for the Linux kernel as well as an I2C library. The tools were originally part of the lm-sensors project but were finally split into their own package for convenience. The library is used by some of the tools, but can also be used by third-party applications. The tools and library compile, run and have been tested on GNU/Linux.

The latest version of the code can be downloaded from: https://github.com/groeck/i2c-tools

How to build i2c-tools for Android platform

Download i2c-tools

$ git clone https://github.com/richardtin/i2c-tools {ANDROID_ROOT}/external/i2c-tools

Compile i2c-tools ONLY

$ source build/envsetup.sh
$ lunch $TARGET-$VARIANT (ex: aosp_arm-eng, aosp_hammerhead-eng)
$ cd {ANDROID_ROOT}/external/i2c-tools
$ mm

• There are 4 binary files - i2cdetect, i2cdump, i2cset, i2cget, and will be installed to {ANDROID_ROOT}/out/target/product/{PRODUCT_NAME}/system/bin folder.

Make new system.img

$ make snod
$ fastboot system system.img

Android.mk
