Protocol
--------
2013-02-22 16:15:03 +00:00
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'
2013-02-22 16:15:03 +00:00
$ cd pc98_usb
2013-02-22 00:53:46 +00:00
$ make
2013-02-22 16:15:03 +00:00
2013-02-22 00:53:46 +00:00
Then, load the binary to MCU with your favorite programmer.
