I think so, if not, very closely related. Some of the pins are configured on bootup with pullup resistors (there are a couple of options) and I was not aware of that. That might be accounting for the weird voltage on 26; my point for taggin along on this thread is that "I thought" all pins were inputs on boot-up (ehem... there shouldn't be voltage on any of them) but that is not true. Well, I noticed a weird voltage on pin 29 GPIO05 (enough to light a low power LED dimly). Joan says that's normal, due to the pullup resistor on 29 being configured on during bootup; perhaps 26 is the same?davenull wrote:is what you're talking about still about me TOP questio "weird voltage 3.0V on GPIO.26" ?
if not, please open your own topic, thank you.
