I am thinking about working on alternative drone controllers. I am looking into making it more easy to use and a natural feel (debating between sensor bracelets, rings, etc.).
The main issue I have is, I've been looking over all the standard RC transmitters that are used to control RC aircraft, but I am not sure what technology is inside of them, what kind of ICs they use for the actual RC signals.
I want more information on how to make an RC transmitter myself, mainly the protocol that's used to send messages, and what circuitry is needed to actually transmit that, what kind of components do I need and how should I implement the software?
I was aiming at doing this as a side project (hobby), but now I have the chance to use it as a uni project as well, so I'd like to give it a shot now, but I lack the proper information before getting started.
I'd rather not take apart my current RC controller and use an oscilloscope to decode the protocol.
Any answers (short or long) and reading material is appreciated.
Other questions, can the protocol be implemented in software on an embedded system (Raspberry Pi, Arduino, Intel Galileo, etc.)? I am asking this because the frequency for these are 2.4 GHz.
This is part of a bigger project, drone related currently, and I could use alternative methods of sending the information, through other wireless means, as the first prototype, suggestions are welcomed.
Need: aircraft RC transmitter protocol info, RC transmitter components & schematics, anything else that might help with the transmission side
because the frequency for these are 2.4 GHz? By
these, do you mean the Pi, Arduino or Galileo? These boards are not confined to using 2.4 GHz. $\endgroup$
