PC98 to USB keyboard protocol converter
=======================================
Target MCU is ATMega32u4 but other USB capable AVR will also work.


Connector
---------

    8Pin mini DIN

    | 5    4  3 |
     \_ 2   1 _/
       \_____/  
     (receptacle)


Wiring: You can change this with ediging config.h.

    Pin mini DIN        MCU
    ----------------------------------
    1  ~RST             PD1
    2   GND             GND
    3  ~RDY             PD4
    4   RXD             PD2
    5  ~RTY             PD5
    6   NC                 
    7   NC                 
    8   5V              VCC




Protocol
--------
Singnal: Asynchronous, Positive logic, 19200baud, Least bit first
Frame format: 1-Start bit(Lo), 8-Data bits, Odd-Parity, 1-Stop bit

This converter uses software method for testing purpose. AVR UART engine will work better.




Build Firmware
--------------
Just use 'make'

    $ cd pc98_usb
    $ make

Then, load the binary to MCU with your favorite programmer.
