Hi,
I've been trying to get my DS1820 temp sensor working but cant seem to get the device to show up om my orange pi zero 2 running Orange Pi 3.0.6 Bullseye
Most info i find starts our with run armbian-config but orangpi doesnt have it. All i got is the orangepi-config but it doesnt have the "Go to the “system” section and select “Hardware” then activate w1-gpio."
so i was looking arround and found you need to enable overlays in /boot/armbianEnv.txt but dont have it aswell but the alternative /boot/orangepiEnv.txt
there i add the
/boot/orangepiEnv.txt
overlay_prefix=sun50i-h616
overlays=w1-gpio
param_w1_pin=PC8 <<<<< not sure about the pin numers
param_w1_pin_int_pullup=1
looking at the output i would say PC8 is correct pin name.

if i understaand correct i need to add the kernel moduels by doing:
modprobe w1-therm
modprobe w1-gpio
after reboot i should see the device show up? using:
ls /sys/bus/w1/devices
but go nothing.
so i check :
root@orangepizero2:~# cat /sys/kernel/debug/gpio
gpiochip0: GPIOs 0-287, parent: platform/300b000.pinctrl, 300b000.pinctrl:
gpio-76 ( |red:power ) out lo
gpio-77 ( |green:status ) out hi
gpio-80 ( |usb1-vbus ) out hi
gpio-166 ( |cd ) in lo IRQ ACTIVE LOW
gpio-210 ( |reset ) out hi ACTIVE LOW
gpiochip1: GPIOs 352-383, parent: platform/7022000.pinctrl, 7022000.pinctrl:
it seems like im missing something fundamentally? can some one point me in the write direction?
