X68000 to USB keyboard protocol converter
|
||||
=========================================
|
||||
SHARP X68000 is a hobby computer released in Japan.(1987-93)
|
||||
http://en.wikipedia.org/wiki/Sharp_X68000
|
||||
|
||||
X68000 keyboard has ALPS linear switches.
|
||||
- DSETK0016CE01 green linear
|
||||
- DSETK0023CE03 yellow linear
|
||||
|
||||
|
||||
Hardware
|
||||
--------
|
||||
Target MCU is ATMega32u4 but other USB capable AVR will also work.
|
||||
You can use PJRC Teensy as dev board.
|
||||
http://www.pjrc.com/teensy/
|
||||
|
||||
Wiring:
|
||||
Mini-DIN Teensy
|

|
||||
pin1 +5V VCC
|
||||
pin2 MOUSE -
|
||||
pin3 RXD PD2(RXD)
|
||||
pin4 TXD PD3(TXD) NOTE: Not supported yet.
|
||||
pin5 READY -
|
||||
pin6 REMOTE -
|
||||
pin7 GND GND
|
||||
|
||||
|
||||
Firmware
|
||||
--------
|
||||
Build:
|
||||
$ cd x68k_usb
|
||||
$ make
|
||||
|
||||
And load the binary to MCU with your favorite programmer.
|
||||
If you use Teensy you can load with PJRC Teensy Loader tool.
