  1. Hi, Yes, iam sure that is a 1wire temp sensor (DS18b20 incl. 4,7kOhm resistor) connected. The output of cat /sys/kernel/debug/gpio is
  2. I have tryed 5 another gpio's and i have installed a pullup resistor 4,7kohm. The result is the same as above.
  3. unfortunately no success i have modified another overlayfile to that then the output of dmesg | grep w1 is and cat /sys/kernel/debug/gpio shows me in the device/tree of w1 i have devices like 00-400000000000 00-c00000000000 w1_bus_master1 but the device numbers changes every minute
  4. Yes. My armbianEnv.txt look so but has no effect. lsmod doesnt show any w1 module. I also have edited the sun8i-a83t-bananapi-m3.dtb and paste and this also have no effect
  5. is it possible to get 1wire over gpio to run with the m3 and armbian?
