# 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 |
(this is a modified copy from [@alvicstep](https://github.com/qmk/qmk_firmware/blob/master/keyboards/kinesis/alvicstep/alvicstep.h))
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.
```
DL2 1 40 VCC
DR1 2 39 A
DR2 3 38 B
DL1 4 37 C
KPD 5 36 G
PGM 6 35
SCL 7 34
SDA 8 33
RST 9 32 BUZZ
WP 10 31 EA
FS1 11 30 ALE
CLOCK 12 29 PSEN
DATA 13 28 r8
14 27 r7
FS3 15 26 r6
16 25 r5
FS2 17 24 r4
XTAL1 18 23 r3
XTAL2 19 22 r2
GND 20 21 r1
```

## Pin Mapping to Pro Micro
The following table is ordered by physical Arduino pin order.
| Arduino | Kinesis | Meaning |
| ------- | ------- | ------- |
| D3 | 36 | G |
| D2 | 37 | C |
| GND | | |
| GND | | |
| D1 | 38 | B |
| D0 | 39 | A |
| D4 | 1 | DL2 |
| C6 | 2 | DR1 |
| D7 | 3 | DR2 |
| E6 | 4 | DL1 |
| B4 | 5 | KPD |
| B5 | 6 | PGM |
| B6 | 21 | r1 |
| B2 | 22 | r2 |
| B3 | 23 | r3 |
| B1 | 24 | r4 |
| F7 | 25 | r5 |
| F6 | 26 | r6 |
| F5 | 27 | r7 |
| F4 | 28 | r8 |
| VCC | 40 | |
| RESET | | |
| GND | 20 | |
| RAW | | |
## 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.
