Trying to get a DHT22 sensor to work on a Raspberry Pi ZERO WH running BUSTER. The demo Python program works on pin 21 (4 is in use by my DS18B20 sensors.) I tried the dtoverlay method, but I don't even get a new w1_bus_master2 directory.
If anyone has gotten the dtoverlay method to work, please tell me how. (I've tried JAVA, but none of those examples work either. JAVA would be my preferred way to access it.)
