BS18B20 Stopped Working! - Raspberry Pi Forums


i got bs18b20 temperature probe, , got work using instructions adafruit. added sample script python app use control things in house , worked fine too, 1 day. , stopped. started beginning, , /sys/bus/w1/devices folder empty, after sudo modprobe w1-gpio , sudo modprobe w1-therm. checked connections , checked out ok multimeter. don't have oscilloscope, can't tell if there's comms going on.

there can debug it?

did run apt-get upgrade or dist-upgrade?

might running system uses "device tree" , needs following line in /boot/config.txt ds18b20 sensors work

code: select all

dtoverlay=w1-gpio 
reboot.
