G'day members,
after doing the obvious, which is looking in the bcm data sheet, I found out, there is a GPIO Pull-up/down Register (GPPUD). And this may really make an external pull-up resistor unnecessary. But I do not know, the given Raspi (Pi 2B rev 1.1) , Raspbian (1:6.6.31-1+rpt1) and/or overlay version does not this feature.
Hence, I do know, a ~50k pull-up resistor is needed on this platform.
Thanks.
