Buttons

[otosan-maker]

Hello, I have tried the test program to use the buttons, IO34 and IO39 works, but IO35 is not. Is there any special thing with IO35?? I think the other button has problems ... IO0, isn´t it?

I tried all buttons using this repository and they work great for me https://github.com/atomic14/diy-esp32-epub-reader Maybe share some code of how you are reading them because all button GPIOs are working alright for me when trying that ePub reader.

Here is an easy to use example

include "Button2.h"

include

define BUTTON_1 34

define BUTTON_2 35

define BUTTON_3 39

Button2 btn1(BUTTON_1); Button2 btn2(BUTTON_2); Button2 btn3(BUTTON_3);

void buttonPressed1(Button2 &b) { Serial.println("1"); }

void buttonPressed2(Button2 &b) { Serial.println("2"); }

void buttonPressed3(Button2 &b) { Serial.println("3"); }

void setup() { Serial.begin(115200); delay(50); Serial.println("Button Demo"); btn1.setPressedHandler(buttonPressed1); btn2.setPressedHandler(buttonPressed2); btn3.setPressedHandler(buttonPressed3); }

void loop() { btn1.loop(); btn2.loop(); btn3.loop(); }
