I have a Raspberry Pi 2 running Raspbian 3.18.11 I connected a DS18B20 sensor via i2c.
Problem is: it does not show up on
i2cdetect -y 1
However, that data from the sensor is available at /sys/bus/w1/devices/28-xxx/w1_slave and seems to be correct (changing when touched).
lsmod | grep shows i2c_dev and i2c_bcm2708
And blacklist.conf is empty.
