Hi. I am not sure this is the right place to post this question, but I’ll try anyway…
Here’s what I would like to achieve; measure temperature using one or more (waterproof) 18b20 sensors operating in 1-wire mode, and display the temperatures on an Inky PHAT.
I got it working for a while, but suddenly when I do
with one sensor connected to the 3V3, GPIO4 and ground pins, I get output like
00-400000000000 00-800000000000 w1_bus_master1
Is there some compatibility issues with the Inky PHAT and these sensors? I’ve spent a lot of time on this already, thinking that it would be really simple to do what I want. It seems not though, maybe I’m doing something wrong?
