I have an ESP32-WROOM-32-N4 and I'm planning to utilize GPIO pin IO0 to power some LED diodes using an N-channel MOSFET.
I understand that IO0 is HIGH at Boot, and to enter programming/flashing mode, it needs to be set to LOW.
- Do it need to be set to LOW just on when esp boot or even after it boots normally i dont need to set to LOW
I'm okay with the fact that it's HIGH during boot, but my concern is whether there will be an issue if I use it in this manner. Specifically, After it boots in normal mode, I intend to use IO0 like any other pin to set it HIGH/LOW.
- will the ESP32 power on in normal mode if I don't connect IO0 with GND during the booting process? e
