Greetings XODers,

I’m here to ask if anyone has managed to get the 4x4 keypad working, or at least how to make a matrix that allows it to be used. I know the keypad has X1-4 going from top to bottom, and Y1-4 going left to right, with the 8 female pins on the flexible cable going (From left to right): X1, X2, X3, X4, Y1, Y2, Y3, Y4.

If anyone has figured how to make a mall matrix, it might be possible to enlarge it to the 4x4 size.

Along with this, I hope to have the numbers be held in a sequence and hopefully displayed on a 16x2 LCD display.

If anyone has any knowledge, please let me know.
