DHT11 with Feather 32u4 Lora - Can't read DHT #180

Closed chrisShick closed 1 year ago

chrisShick commented 3 years ago

I followed the adafruit tutorial on setting up a DHT11 (3 pin) with the feather. The library just gives nan for both. However, when I run the library with an UNO it works just fine. Any ideas here? My thoughts are around the underlying timing issues.

I have a similar problem, I also get a NaN for both on my Uno. But if I downgrade the library from 1.4.1 to 1.4.0, it magically works

Can not recreate the issue. Running the DHTtest.ino sketch on a Feather 32u4 with DHT11 on pin 3 runs as expected:
