Hi all, has anybody succesfully used Omnia (or any other Turris, I suppose? ) with DHT22 (or DHT11) sensor?
I’ve bought one preinstalled on a board ready with pullup resistor, so I’ve connected it to +3.3V, GND and GPIO 42 pins and have been trying to make it work for a while
As adafruit libraries do not support Turris, I figured this would be a way to go:
so I instaled the driver and now I’m stuck figuring out what to do about device trees.
Most tutorials online I’ve been able to find are Raspberry PI related and don’t seem helpful.
I’ve come accross some mentions of DT overlays to be placed into /boot/overlays folder.
This folder, however, doesn’t exist on my Turris and I suspect it wont be as easy as just creating it… and I’m not at all clear on the topic of creating the overlay file anyway.
The idea of editing the global device tree doesn’t sound great either.
