The DHT22 arrived today and it's mostly good news, I'm almost there!
My RX board now initialises properly and goes on to display as it should indoor and outdoor temps, humidity etc. The outdoor ones are exactly as I expect but there's something wrong with the indoor ones - the temperature is reading a pretty cold -2507.9 degrees and 4071.3 for humidity!!
I've rechecked wiring & connectors, all's ok and there's 5.0v at pin 1. Is there anything else to check or is it likely to be a faulty DHT22??
Allan - getting excited now that I'm very nearly there.....
