Is it possible to use Flash button on esp board as input?

[lazarvgd]

Hi there,

Recently I found that I need some kind of toggle on esp8266 to turn on device, I have added pulldown resistor and it worked, but I am wondering is it possible to use onboard flash button as input? If yes, can somebody point me how to configure it?

Thanks

You have to show the module, since not all boards have that button. But if it is the button to enable boot mode: that one is connected to GPIO0 and it can be used with the machine.Pin() class. Doing that, you might have to deal with debouncing. But a search for that word in the forum will retrieve the needed information.
