+# Viet's Kinesis + Pro Micro
+
+July 2020
+
+This work is inspired by `alvicstep`'s solution. Instead of hooking up the Kinesis to a Teensy 2, this one hooks it up to a Pro Micro.
+
+## Kinesis Board Layout
+The following is a reinterpretation of [@chrisandreae](https://github.com/chrisandreae/keyboard-firmware/blob/public/hardware/kinesis.h)'s work.
+
+### Used Pins
+* 8 columns mapped to output pins 21 - 28
+* 16 rows mapped to 4 input pins: pin 39 - 36. Rows are traversed by iterating and setting 16 values from 0000 to 1111. 
+* 4 leds (e.g. capslock) mapped to input pin 1 - 4
+* keypad key mapped to pin 5
+* program key mapped to pin 6
+* `VCC` mapped to pin 40
+
+### Matrix Configuration
+The matrix configuration of the columns and rows on my Advantage is as follows:
+
+|        | row 0  | row 1  | row 2  | row 3  | row 4  | row 5  | row 6  | row 7  | row 8  | row 9  | row A  | row B  | row C  | row D  | row E  | row F |
+|  ----- | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | -----  | ----- |
+|  col0  | F6     | F8     | F7     | 5%     | 4$     | 3#     | 2@     | 1!     | =+     |        |        |        |        |        |        |       |
+|  col1  | F3     | F5     | F4     | T      | R      | E      | W      | Q      | Tab    |        |        |        |        |        |        |       |
+|  col2  | Esc    | F2     | F1     | G      | F      | D      | S      | A      | CapsLk |        |        |        |        |        |        |       |
+|  col3  | F9     | F11    | F10    | B      | V      | C      | X      | Z      | LShift | Up     |        | Down   |        | [{     | ]}     |       |
+|  col4  | F12    | ScrLk  | PrtSc  | Right  |        | Left   | Insert | ~      |        | 6^     | 7&     | 8*     |        | 9(     | 0)     | -_    |
+|  col5  | Pause  |        |        | LAlt   |        | Home   |        | End    |        | Y      | U      | I      |        | O      | P      | `\|`  |
+|  col6  |        |        |        | LCtrl  | Delete | Bksp   | RCtrl  | Enter  | Space  | H      | J      | K      |        | L      | ;:     | '"    |
+|  col7  |        |        |        |        | RGUI   |        | PageUp |        | PageDn | N      | M      | ,<     |        | .>     | /?     | RShift |

+
+In the code, keypad and program keys are mapped respectively to col0 and col1 of row C, the 12th row.  
+
+### Omitted Pins
+There are pins that we currently omit:
+* serial eeprom clock line mapped to pin 7
+* serial eeprom data line mapped to pin 8
+* EEPROM write protect mapped to pin 10.
+* foot switch 1 mapped to pin 11 
+* PS/2 clock mapped to pin 12
+* PS/2 data mapped to pin 13
+* foot switch 2 mapped to pin 17
+* foot switch 3 mapped to pin 15
+* audio mapped to pin 32
+
+### DIP Socket
+Here's an ASCII drawing of the 40 pin DIP socket.

+
+## Notes
+
+* The rows are multiplexed. Instead of reading them out, one sets the row value and corresponding column values are returned through r1-r8.
+* On my keyboard, the keypad and program key have dedicated pins. Since row 12 had no mapping in the physical matrix, there's a code override injects the keypad and program pins to the first two bits in the matrix.
+* I've experimented with debouncing approaches. The current setting delivers a snappier feeling than Kinesis's factory default for me.
