During a sunday picnic, I was thinking about new design of ArcuCopter.And I asked myself:"Why shall we continue to use RC transmitter consoles? Couldn't we use a computer, or an iphone in the ISM band? We will have all-in-one architecture: FPV,commands,telemetry".
And in fact, I think we can think about that.
I am designing a new architecture for Arduino, with WiFi module. All the data (telemtry, commands, and video) will be on WiFi channel. On the ground, a singolo laptotp or a smarphone, with a tracking antenna, will handle everything: FPV, commands and telemetry data.
In this regard, I have a question. What kind of signals the RC receiver outputs? Or, doing from another side, which kind signal we have to put in the Arduino ?
I think the choice is wide. I mean, we can do whatever we want. The problem maybe is the protocol.
If I would re-use the current code, which kind of signal I must send to APM for commands (e.g. throttle, pitch,yaw, and so on)? Are they PWM values? Does the APM have PWM decoder in software or hardware?
