ESP8266 Community Forum

I have written up some notes on how to use the GPIO0/GPIO2/GPIO15 pins for general I/O
Using ESP8266 GPIO0/GPIO2/GPIO15 pins

Thanks, very good and clear article.
Any addition re: GPIO16? I guess when not using deep sleep, GPIO16 can be used as a regular I/O pin, right?

Hi, great write up - it might just be worth a note for compleatness, that with the switch in place, if it is closed you canot flash the ESP, however open you can. Not a problem in it's final application.
