An SBUS message consists of 25 UART bytes, and carries +16 proportional channels with 11 bits each, and 2 digital channels +(boolean, 1 bit), and flags which represent current communication state. +Proportional channel values typically are in the 192..1792 range, but +individual implementations may differ. +''' + +from .pd import Decoder |
