= 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 In this how-to i do , we use a program that reads and decodes EDID information from EEPROM display. This program was tested in [http://releases.linaro.org/platform/linaro-m/headless/final/linaro-m-headless-tar-20101108-2.tar.gz Linaro Headless] with [[Linux Kernel 2.6.35.y|Kernel 2.6.35.y]] and [[How to get the Poky Linux distribution|Poky Linux distribution.]].<br>
NOTE: This program is a beta version, it decodes E-EDID follow Standard Release A-1 using i2c-dev driver. There are some functionalitise that are not implemented (see code comments) and other new ones that appear in other revisions. Besides it only parse the first EDID 128 bytes block. But this code is only a sample to learnt use I2C.<br> More information about [http://en.wikipedia.org/wiki/Extended_display_identification_data EDID].<br>
