  Solder X wires between FPC breakout board to the Microcontroller.

  For me X = 24. and i had poor experience with digital pin 33 and digital pin 25. this is attributed to set up issues which i am not

  sure how to solve so i just switched pins.
  
  i used wire wrapping wire for this, as i wanted to maintain flexibility and flatness of the resulting harness so i could reposition it later. its also less distubing to look at.

  Load the keyboard decoder sketch

  Follow this instructable, https://www.instructables.com/id/How-to-Make-a-USB-Laptop-Keyboard-Controller/ you can jump to step 8. i used the teensy 3.2 decoder sketch and uploaded it through arduino+teensyduino.

  
  Load the teensy3.2 matrix decoder, I edited it a bit for use with excel so i get a nice layout i can keep coming back to later. modify on your own as required.

  
  get the 2 pins associated with each keypress. Generate 1 pair for each key till all assigned. 

   
  You can use an excel table to sort things easily. I sorted the results into 8groups of 16keys. At this point the numbers are digital pin numbers. Save this in your spreadsheet to come back to it later.

  Re assign them numbers for a new coordinate system with origin (0,0) (row=group, column=key), this would be what kbfirmware.com is looking for. 

  
  From the earlier pin numbers map it to the port assignments, you will use this to modify the keyboard config.h files later.
