Yes, there are differences on each machine.Symoon wrote: ↑Sat May 28, 2022 2:34 pm Does that mean it should be rather early when the signal goes "up again"? (knowing that, like Dbug said, it could depend on each machine). That would be fine with the example where I wondered where it began: it seems the earlier it is, the closer to the writing it is.
But because VIA's CB1 (input) is set to detect the rising edge only and each bit length is measured as time between 2 rising edges, for me the differences theoretically should be minimal i.e. for both standard protocols (fast & slow) it doesn't matter actually at what voltage the rising edge will be detected.
