gpio usage #519

Open lawashnik opened 3 years ago

lawashnik commented 3 years ago

Hi. How can I programm gpio pins? Besides using serial bridge I want to manage gpio's state over wifi. Is it possible? Like curl requests or something..?

uzi18 commented 3 years ago

@lawashnik Actually it is not supported

lawashnik commented 3 years ago

I find something like solution. I can change reset pin to any and its state become high. But previous pin state doesn't become low. It becomes low only after resetting esp. Better than nothing I guess.

How many gpios you need?

Only one.

Can add api to set/reset this pin if you need

I have also interest in switching gpio through the webapi. I try to build an automated esp32-cam testing stand. If a firmware over OTA fails i would like to use this project to flas a default image. The problem is i need to toggle power and connect GPIO0 to GND to programm the esp32-CAM on demand.

The ability to control even one GPIO via API would be great.

It is possible. Someone should write it ;)
