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'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)

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.
