I have the eval board of the 7842 & 7511.
My source is connected to the VGA port and i would like to know if it is possible to read the EDID of the source from this port ?
The EDID information comes from the sink, the repeater code copies it to the internal EDID memory in the ADV7842. AVES is able to extract the EDID memory from ADV7842 and display it using the EDID editor. You can also view the EDID data directly in AVES by looking at the ADV7511 EDIDmemory tab.
You can use an external I2C monitor to capture or pull the EDID as the VGA source reads the EDID data from the ADV7842.
The latest EDID editor can be found at http://ez.analog.com/docs/DOC-2143
