w1-gpio cable connection



  • Hi,

    I try to connect a DS1820 (Temp-sensor) with the expansion dock(inc. onion omega).

    I have build my own openwrt with this tutorial.
    I have added the modules w1-gpio and w1-therm.
    The w1-* modules are loaded.

    On the pins GND/3.3V/GPIO1 I have connected the DS1820 inc. Resistor as I use it on Raspberry PI.

    But I don't find the output of this sensor via "ls /sys/bus/w1/devices". No device is available.

    Have anyone a idea why? Must I configure a kernel parameter to use the GPIO for 1-Wire?

    Thanks
