5V 1-wire Bus

Post by mob » Thu Oct 27, 2016 12:23 pm


I need to set up a 1-wire bus with 5 Volts on GPIO4, since I have quite long cables. See http://www.fhemwiki.de/wiki/Datei:Levelshifter.png for the wiring diagram.

Where can I find the 1-w pullup resistor to 3v3 on the PIco? By removing it I should be able to use GPIO4?

Or is there an easier way to get an 5V 1-wire bus?
