When using Ticker, must attached function's return type be void?
When I changed MotorDriver::communication's return type to void , build succeeds. But when I using int, build would fail. Is this a specification or my mistake? The compiler says "no matching function for call to 'mbed::Ticker::attach(mbed::Callback<int()>, float&)'" on Ticker.h 95

Yes, return type must be void as the function signature shows:
attach(Callback<void()> func, IrqType type=RxIrq)
