DDMI (Differential Data Multiple Interface)

DDMI (Differential Data Multiple Interface)

Overview

DDMI (Differential Data Multiple Interface) is a work-in-progress (non-)specification for differential data transfer over a 19-pin HDMI® style connector.

This repo contains the pinout for the DDMI connector and the DDMI Pmod™ compatible module.

This project was inspired by DVI-PMOD, SmolDVI and the ULX3S GPDI connector.

ddmi's Issues

HDMI license.

Hi

Sorry to say this but calling HDMI "DDMI" does not get around the HDMI licensing. As long as you are using HDMI connector and generating signals that can be received with HDMI monitor you need to be HDMI adopter and pay the fees.
