SBus Servos — Plane documentation
Questions:
Where can I find more info about RC_Receiver chip? Datasheet?
SBUS uses an inverted serial polarity. Is this supported for our MCU? Can we just invert in code or does it have to be hardware inverted?
How many channels do we need? Is there any limitations with certain protocols?
SBUS is one of the possible communication protocols that come from the RC_Receiver.
Seems like FutabaRC.com site is down and everything links to that for SBUS documentation
SBUS uses a standard Serial protocol (?) (even parity, 2 stop bits, 100000 baud). Inverted polarity so it must be inverted.
Each servo has 11 bits meaning a maximum of 2048
