Problem with keypad library in 2x8 keypad

I built a custom 2x8 keypad to use for a project and i’ve been following the examples from the arduino keypad library examples folder, and I’ve gotten stuck. When I go to compile I get the following error:

error: no matching function for call to 'Keypad::Keypad(char [2][9], byte [2], byte [8], unsigned int, unsigned int)'hardware\libraries\Keypad/Keypad.h:54: note: candidates are: Keypad::Keypad(char ()[5], byte, byte*, byte, byte)

hardware\libraries\Keypad/Keypad.h:53: note: Keypad::Keypad(byte*, byte*, byte, byte)

hardware\libraries\Keypad/Keypad.h:52: note: Keypad::Keypad()

hardware\libraries\Keypad/Keypad.h:50: note: Keypad::Keypad(const Keypad&)

when I compare this to the library file, I notice that it is missing one of them options, the one I am using for allowing to customize

Keypad(char userKeymap[MAX_ROWS][MAX_COLUMNS+1], byte row, byte col, byte rows, byte cols);

It doesnt seem happy that i’m using a digit other then - [5] (using [2][9])

Does anyone know what the problem could be? I apologize in advance if I posted this in the wrong forum.

What I have so far:

#include <Keypad.h>

#define ledPin 13

//define the symbols on the buttons of the keypads
char hexaKeys[2][9] = {
  "01234567",
  "890*OX><"
  
};

// Connect keypad ROW0, ROW1, ROW2 and ROW3 to these pins, 
// eg. ROW0 = Arduino pin2.
byte rowPins[] = { 3, 4 };

// Connect keypad COL0, COL1, COL2 and COL3 to these pins, 
// eg. COL0 = Arduino pin6.
byte colPins[] = { 12, 11, 10, 9, 8, 7, 6, 5 };

// Initialize an instance of class NewKeypad
Keypad customKeypad = Keypad(hexaKeys, rowPins, colPins, sizeof(rowPins), sizeof(colPins));

void setup()
{
  digitalWrite(ledPin, HIGH);
  Serial.begin(9600);
}

void loop(){
  char customKey = customKeypad.getKey();

  if (customKey) {    // same as if(customKey != NO_KEY)
    Serial.println(customKey);
  }
}

Hello!

This is actually a bug that we’re trying to fix right now.

Maybe you could wire it as a 4*4 and have it work with the current version? [If you have access to the pins.]

//define the symbols on the buttons of the keypads
char hexaKeys[4][5] = {
  "0123",
  "4567",
  "890*",
  "OX><"
};

Unfortunatly I dont think I can make it work with 4x4, what is the current maximum colums? I can maybe take out some of the buttons and get it to work with 2x7 or 2x6.

Would another option be configuring 2x 1x8 keyboards? Can you assign custom key layouts to more then one keyboard?

thank you for the info.
