need help with 10x11 matrix

[Anonymous]

So I've been trying to figure this out its an arachnid board
has 10x11 ribbon .
When I go through setup 20 and 1 doesn't register
I'm using a mega 2560
Heres what i upload to it
Any help would be appreciated
Thanks
Chris

Can you tell me the type of the arachnid board? As the matrix of a "professional" Arachnid board is 11x8. There is space in the 6th row (pin 14 on the board connector) to connect the phisical buttons to.

Hi Chris,

Thinking that you might have used a different matrix I started looking into your code. I've seen you correctly adjusted the number of rows and collumns. You changed the input pins of those as well.

However you did not expand the lookup table to 10 rows and 11 collums, so everytime you hit a number outside the 8x10 matrix no payload was send over the serial connection. So it would not register.

Please try this code and let me know if it works, I had to get a little crazy with the symbols since 10x11 is quite a large matrix. I don't know if this is supported or not. If not please try different symbols until it works. (you can test the connection in de serial monitor build in to the arduino IDE)

}
return key; // returns the key pressed or 0 if none
}

Some dartboards even have diferent alocations for the inner single 20 and outer single 20. (and all of the other numbers)

the way I solved this was placing the same character in the lookup table.

Kind regards,
Huub

Hi, hope you did not give up on this project allready, I had it working a few years ago with a Arachnid Galaxy 1 Cabinet. Let me dig in to my back ups to see what my code used to look like.
