I tried to read all the discussion for the previous series, but still don't quite understand why do we need the infrastructure to be that complex. I mean Wiegand is point-to-point connection, so why do we even need bus/controller/device abstractions at all? There will be always just the single device per controller, right? -- Kind regards, Evgeny Boger CTO @ Wiren Board
