uint8 RC_INPUT_MAX_CHANNELS = 18 # Maximum number of R/C input channels in the system. S.Bus has up to 18 channels.
uint64 timestamp_last_signal # last valid reception time
uint32 channel_count # number of channels actually being seen
int32 rssi # receive signal strength indicator (RSSI): < 0: Undefined, 0: no signal, 100: full reception
bool rc_failsafe # explicit failsafe flag: true on TX failure or TX out of range , false otherwise. Only the true state is reliable, as there are some (PPM) receivers on the market going into failsafe without telling us explicitly.
bool rc_lost # RC receiver connection status: True,if no frame has arrived in the expected time, false otherwise. True usUally means that the receiver has been disconnected, but can also indicate a radio link loss on "stupid" systems. Will remain false, if a RX with failsafe option continues to transmit frames after a link loss.
uint16 rc_lost_frame_count # Number of lost RC frames. Note: intended purpose: observe the radio link quality if RSSI is not available. This value must not be used to trigger any failsafe-alike funtionality.
uint16 rc_total_frame_count # Number of total RC frames. Note: intended purpose: observe the radio link quality if RSSI is not available. This value must not be used to trigger any failsafe-alike funtionality.
uint16 rc_ppm_frame_length # Length of a single PPM frame. Zero for non-PPM systems
uint8 input_source # Input source
uint16[18] values # measured pulse widths for each of the supported channels
