I'm new in Raspberry... I have a problem, I'm trying to connect a DS18B20 temperature sensor to a Raspberry but I can't see anything start with 28-... in /sys/bus/w1/devices
I've run
sudo modprobe w1-gpio; sudo modprobe w1-therm
I have this in my /boot/config.txt
__dtoverlay=w1-gpio-pullup,gpiopin=4__
If I run the example from More than 10 DS18S20 I get this:
*** Error Unable to detect Logic level 1. No pull-up ?
Please let me know what I'm doing wrong.
