my friend has a Quadcopter, and this Quadcopter send video to radio Control.
a lcd is connected to Quadcopter using hdmi
but we don't need this video :)
we want send data using this path , then We do not need to design a 5-kilometer transceiver.
but the problem is that, i dont know how send data using microcontroller to hdmi ( Quadcopter side ), and receive my data from hdmi ( radio Control Side )
Is this possible?
Is this a reasonable approach?!!
