Overview
This How-To is meant to be a starting point for people to learn use I2C for IGEP v2 devices as quickly and easily as possible. For this how-to i do a program that reads and decodes EDID information from EEPROM display. This program was tested in Linaro Headless with Kernel 2.6.35.y and Poky Linux distribution.
More information about EDID.
Feedback and Contributing
At any point, if you see a mistake you can contribute to this How-To.
Check I2C Devices
In this How-to i used pre-compiled modules, because: it's quick and it works. All versions of Linux are supported, as long as I2C support is included in the kernel.
To make sure that I2C driver works well, follow the next steps (tested in Linaro Headless):
sudo apt-get install i2c-tools i2cdetect -l
Compile
Run program
