I think so, 3 bits was a shoot from the hip number. I'm manchester encoding so I think I'll have at least one '1' bit per three, and my preamble, sync byte and stop byte are all 'balance'. Hmmm, maybe I should sample for a couple more bits? Three is the bare minumum. Thanks, Kevin Olin Lathrop wrote: > > > I over sample for the time it takes to transmit three bits.
