Ubuntu Server One Wire DS18B20 Sensor Problem

[Soleyman]

Hello Raspberry lovers

I have Raspberry Pi 3 Model B V2

Installed Ubuntu Server 19.10 (GNU/Linux 5.3.0-1017-raspi2 aarch64)

I want using DS18B20 sensor as same as

https://www.electronicshub.org/raspberr ... -tutorial/

I can't see anything in /sys/bus/w1/devices/ directory

try several time and play with gpiopins (GPIO 7 pin 7, GPIO 4 pin 16, ...)

Code: Select all

w1-gpio
If you require the external pullup
dtoverlay=w1-gpio-pullup,gpiopin=x,pullup=y
otherwise
dtoverlay=w1-gpio-pullup,gpiopin=x
(where x and y are gpios).

but I can see DS18B20 Sensor in /sys/bus/w1/devices/.

How can add it in Ubuntu for see it's work ?

Thank
