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
By defaul, all Linux Kernel support I2C bus via i2c-dev driver
Compile
Run program
Under construction
