An arduino sketch, created for an Arduino mini, that makes a serial keyboard out of a C64 keyboard.
It makes use of the cool [http://playground.arduino.cc/Code/Keypad](Keypad library).
Sorry, I have lost my notes on how to connect the keyboard to the Arduino mini.
I started from the C64 documentation, but is is wrong:
- https://www.c64-wiki.com/wiki/Keyboard
- http://www.zimmers.net/anonftp/pub/cbm/documents/cables/c64-keyboard.txt
From the code:
byte colPins[COLS] = {2,3,4,9,6,7,8,5};
byte rowPins[ROWS] = {10,11,12,13,A0,A1,A2,A3};Columns would be A through H Rows would be 0 to 7
Here's an image of the keyboard interface on the breadboard version of my BASIC computer. You can see the Arduino mini tucked away under some cables. You can see a small part of the keyboard on the top left.
