Re: Simple wifi web server - hygrometer with DHT22 sensor
![Post Post](./styles/FLATBOOTS/imageset/icon_post_target.gif)
Sorry for pushing an old thread.
Quick question: Is it possible to wire the DHT22 to another Pin than GPIO2?
The documentation says, that GPIO has two more functions as: I2SO_WS and U1TXD.
For me I need UART1 for debuggung purposes, so GPIO2 is reserved for me.
What does I2SO_WS mean? Is it nessesary for the DHT22? Or is there another logic, why everyone is using GPIO2 for the DHT22.
Thanks!
