Hi all,
I trying many days set up temperature sensor work, but no luck (
Orange PI PC Armbian 20.11.3 Focal with Linux 5.9.14-sunxi
try many pins, 3 and 5 V , but same result, no sensor read. No any resistor, 1 sensor
armbianenv:
overlays=w1-gpio usbhost0
param_w1_pin=PD14
param_w1_pin_int_pullup=1
output:
root@orangepipc:~# gpio readall
