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
