Is it possible to detect multiple buttons pressed at the same time

[lzakrzewski]

Hello,

I'm trying to figure out if there is a way to detect that many keys are pressed simultaneously, so I can support combinations of pressed keys.
Any idea?

Thanks

Last week, I created a similar library for a PoC. To improve it further, I was reviewing the issue pages of similar libraries when I came across your question. I added this feature to my library, so if it helps you, I'm sharing the link and implementation suggestion below.

https://github.com/arastaskiran/RustyKeypad/

#include <Arduino.h>
#include <rusty_keypad.h>




void textChange(String text)
{
  Serial.println(text);
}

void multipleKeys(String text)
{
   Serial.println(text);
}

void setup()
{
  Serial.begin(9600);

  RustyKeypad::addTextChangeListener(textChange);
  RustyKeypad::addMultipleKeyListener(multipleKeys);
  RustyKeypad::setType(RKP_INTEGER);
  RustyKeypad::enable(); 
  
}

void loop()
{
  RustyKeypad::scan();
  // put your main code here, to run repeatedly:
}
