Futaba S.BUS protocol

Post by art »

Is there only one variant of Futaba S.BUS protocol where 25 bytes message with 0xF0 startbyte and 0x00 endbyte? I use Futaba R6108SB, and it transmits 26 bytes with not 0xF0 startbyte and still 0x00 endbyte.

First byte should be 0x0F I believe. What start byte do you see? Is the second byte 0x0F?

Which bit of your bytes is the least significant bit (first bit after the start bit)?
