[Owfs-developers] "Optimal" DS2406 input circuitry?

2014-04-28 Thread Johan Ström
Hi! I've been experimenting for a while to get good results with a DS2406 configured for input, utilizing the edge detector latch feature (this would probably apply to DS2408 which also has this feature). Since this haven't been as simple as "connect the switch between GND and PIO", I'd thought I
