EN and BOOT Buttons

Postby Ian James » Wed May 23, 2018 11:43 am

Is it possible to use the EN and BOOT button on the WROVER KIT as general IO after powering on?

I wanted to test the gpio routines using one or both of those inputs

I have good news and bad news!

Bad news, the EN button is connected to the EN pin on the ESP32, so pressing it will reset the ESP32.

Good news, the BOOT button is connected to GPIO0 (which is also a bootstrapping pin to set the boot mode), so pressing it will pull GPIO0 low. You can use this as a general purpose button after your firmware is running.
