pinout for switch profile about pedalinomini HOT 3 CLOSED

Display mode button is the built-in BOOT button (GPIO_NUM_0) and it is not changed.
There is not too much GPIOs available: 23, 1 and 3.

You can try to play a little bit with the RIGHT_PIN and LEFT_PIN definition into Pedalino.h

#define FACTORY_DEFAULT_PIN GPIO_NUM_0
#define RIGHT_PIN GPIO_NUM_23
#define CENTER_PIN GPIO_NUM_0
#define LEFT_PIN GPIO_NUM_23

If you are not using MIDI_IN (GPIO_NUM_15) or MIDI_OUT (GPIO_NUM_4) or USB MIDI (GPIO_NUM_18 and GPIO_NUM_19) you could have more available GPIOs. In this case remember to remap them to somenthing else not used.

Thank you for your quick responce. I have found the GPIO 1 and 3 as TX0 and RX0. Can I use GPIO 2 as CENTER_PIN or will I damage the board.

To use GPIO 1 and 3 I think you need to disable serial debug in platformio.ini
Delete or comment the following lines:

-D DEBUG_ESP_PORT=Serial
-D CORE_DEBUG_LEVEL=3

Yes, you can use GPIO 2 but consider that is connected to the board led and it is used as output by PedalinoMini.

Change

#define WIFI_LED 2

in WifiConnect.h too
