HDMI cec

Recommended Posts

I was very happy to hear that ASUS took the HDMI cec more seriously than in the first generation, where the cec was only for the S version.
But what next?
How to control HDMI from a shell? How to read the status with the shell?

In the case of other distributions, e.g. ODROID, I met a fantastic solution and it was possible to control HDMI cec signals, for example in this way:
echo 0x40 0x04> / sys / class / cec / cmd
the above command turned on the screen.

Will I get a ready and working solution for Tinkerboard 2?
