Well I’m gonna go out on a limb and say you are gonna be the first to attempt this in the world. So welcome to a journey into uncharted waters. I’m in for the ride… let’s figure out how to make it work!!
First thing we (or at least I ) need to do is get up to speed on the difference between a flysky rx signal and a frsky sbus signal. Does anyone have any links technical information which describe the output signal of flysky in detail. Is this ibus? I have no current knowledge base in flysky so I need to learn some stuff.
Which pins we are gonna use is easy once we know what the signal looks like and how to handle “hearing” it in code. You basically only have the clk programming pin as an option, or you could remove one of the leds and it’s current limiting resistor and grab a mcu pin there. But I have the feeling we are going to need some code to support. So maybe for testing… let’s keep it simple and use clk and a plug of some sort to be able to disconnect the rx as needed during the figuring this all out process.
