EDID Emulator

The current Design has an error (I2C Pull Ups are missing) and will be corrected while the code is in development. 

The (not finished Code) is available at GitHub: https://github.com/MikaSchaechinger/EDID_Emulator 

This Adapter is connected between a HDMI/DVI source and a Display replaces the EDID and Hotplug Detect of the Display.

Use cases:

• Keeping monitors connected to a PC while switching between different PCs with an inexpensive HDMI switch.
• Controlling the display settings when using an HDMI splitter.
• (Hopefully) use the HDMI Port of the TAng Nano 9k Dev board as a Input
• Create and save multiple EDIDs over Serial Interface
• Clone EDIDs of other Displays
• Inspect and read out EDIDs over Serial Interface

It has a USB-C Connector to access the Serial Interface, and two HDMI Ports for Input and Output.

The PCB is a 6-Layer PCB, so the TMDS lines have enough shielding.

It also provides a tiny formfactor with a PCB size of only 22,3mm x 33,7mm
