And there isn't a 5V source in the cable so I don't see how it could be the hotplug detect wire. I think I2C needs two wires, not "one wire and a ground". There's no reason for this to have Ethernet or Audio Return. According to the video, the TX0,1,2 and CLK pins are required but an HDMI cable could have some optional ones including DDC/I2C, HEC (ethernet), ARC (audio return), or CEC/hotplug ( see diagram from video below). I watched HDMI 2.1 & TMDS Crash Course and while this is a proprietary connection I think it's possible that the additional wire would be one that is part of the HDMI spec. But what about the one just labeled data? With three TX pairs and a TxClk pair this sure looks like HDMI to me.Īnd I tested the one labeled GND and it is, in fact, connected to the metal casing for the unit. and then one labeled GND and one labeled Data. Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also comes with a micro SD card holder with dedicated SPI interfaces.

I found a pinout for the connector (see below - top row), and it has Tx0-/+, Tx1-/+, Tx2-/+, TxCLK-/+. SETUP GUIDE GET STARTED Main Features The MKR Zero board is a great board for getting started with various music projects. It has an LCD panel that displays information from this system but I'd like to get it working with a different display. The 2009 Hyundai Genesis has a combo CD player / stereo / Navigation / car information system.
