PC98 to USB keyboard protocol converter
=======================================
Target MCU is ATMega32u4 but other USB capable AVR will also work.
Connector
---------
8Pin mini DIN
___ ___
/ |_| \
/ 8 7 6 \
| 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.
