[Orange Pi PC 1-Wire]

I am trying to get an Orange Pi Lite to work with a DS18b20 1-wire temperature sensor.  I have resolved that I am using the correct pins on the header and I can toggle an LED on one of the GPIO pins with "gpio write".

 

I have uncommented the lines mentioned in this post (above) in modules.conf.

 

When I run dmesg I see:

 W1-SUNXI: Added w1-gpio on GPIO-20

   and

 Driver for 1-wire Dallas Network protocol.

 

I do NOT see this line in dmesg:

 W1_GPIO: added w1 master on GPIO20

 

Another point of confusion for me:  When I run "gpio readall" I do NOT see any pin called GPIO20.

 

I am running Armbian 3.4.112-sun8i

 

I have looked at some Armbian forum posts talking about modifying the "lime.bin" file using bin2fex and fex2bin but I have not made those changes.

 

Any help would be appreciated.

 

Thanks ... Mark
