SUN Type5 keyboard USB converter
[Japanese page is here]

What is this?
This is an interface converter to use the SPARC Station's old keyboard as USB keyboard.
I use AVR-USB to implement this converter. thank you!

This type of keyboard are habitue in the dump site today. It has a lot of keys without meaning(it's so cool!). You should pick it up from dump site if you don't have it yet. :-)

Firmware can download from here.


Features
You can use SUN keyboard as a typical USB keyboard. Device driver is unnecessary. Volume keys also effective(I confirmed it on Ubuntu Linux. but Windows driver might not recognize it.). Some of the SUN special keys is mapped to the Windows key.

Above photo is an example of a Japanese keyboard, if you use an English keyboard, it's available if you comment out "#define JAPANESE_KEYBOARD" at "main.c".

A complete list of the SUN keycode and USB Usage ID mappings are below of this document.


How to use of Key Macro.
Key macro can be recorded to 4 banks. The number of keystrokes that can be memorized to each bank is up to 63 Up/Down strokes. The left of keyboard is allocated like shown below.

When you want to start the keystroke logging press "HELP" key.
To keep a record, press one of the "Save#1 .. #4" key.
If you want to reproduce recorded strokes press one of the "Run#1 .. #4" key.
Keystrokes doesn't disappear even if it turns off power if it save once because the keystroke is keep in EEPROM

When the number of record characters exceeds it to the limitation (63 strokes) without saving it after the record starts (HELP key pressing), the record operation is canceled automatically. When cancel occurs short beep sound inform you from the keyboard.
Of course, this can record modifier key.


Using this firmware
Attached hex is bilded for ATMega168. Please remember that write the .eep file. I think that this can be run with only rebuilding on ATMega48/88, because program memory consumption is only 3KB and EEPROM consumption is 256B.


Example implementation
very simple!


Connectors in the upper-right corner is not needed. it's only for debugging.
Mini DIN 8 connector pin-assignment is 1: GND, 2: GND, 3: +5 V, 4: mouse signal, 5: RxD, 6: TxD, 7: GND, 8: +5V.

(*1)These are defined as noted by "HID Usage Table v.1.12", but useless in windows environment.
(*2)These are not defined in "HID Usage Table".
(*3)very confusing !


any problem or question?
please contact hogeman at gmail or My Diary(Japanese). I can read English a little.
