Downloading EDID with Arduino

Hi All,

I have some LCD s that would like to make adapters to be able to use. But I need to download their EDID since the datasheets are not clear enough for me to create modelines.

These LCD s have I2C port which carries the EDID. But I dont know how can I download all edid information. And even if I download how in I dont know which format I have save it to see them with EDID viewing/editing application.

Are there already any codes available for this? I dont even know which registers I should query to get for a specific data.

Thanks

Google "EDID protocol" and "DDC2" - that should get you started.
