Here’s an informative tutorial from Darrell Tan’s blog irq5.10 exploring HDMI CEC with a Raspberry Pi.
One interesting feature in the HDMI CEC specifications is Remote Control Pass Through, which allows button presses on the remote control to be passed through to HDMI-connected devices. I thought this feature could be used to unify the various remotes in my living room.
As a quick and dirty way to check out the capabilities of my TV, I used a Raspberry Pi which has a HDMI connection that can be software-controlled. This also meant that I didn’t have to build my own CEC transceiver circuit.
