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:

Any help?

Thanks!

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

Hi,

mmm

Ok, resolved

after I add outboard pullup , immediately :

[292751.493482] w1_master_driver w1_bus_master1: Attaching one wire slave 28.00000615392c crc ca
[292751.613810] w1_master_driver w1_bus_master1: Attaching one wire slave 28.00000615191f crc 86

 

It seems no internal pullup work on 5.9.14 ..

Regards.
