# 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
|
||
|
|
|
||
|
|

## 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.
