+Sun to USB keyboard protocol converter
+======================================
+Target MCU is ATMega32u4 but other USB capable AVR will also work.
+Supported keyboards: Sun Type 5 Keyboard, CTCSP SHORT TYPE KEYBOARD(CKUB)
+

+ ----------------------------------
+ 1 GND GND
+ 2 GND GND
+ 3 5V
+ 4 RX/TX(Mouse)
+ 5 RX PD3
+ 6 TX PD2
+ 7 GND GND
+ 8 5V VCC
+
+
+Protocol
+--------
+Singnal: Asynchronous, Negative logic, 1200baud, No Flow control
+Frame format: 1-Start bit, 8-Data bits, No-Parity, 1-Stop bit
+
+ AVR USART engine expects positive logic while Sun keyboard signal is negative.
+ To use AVR UART engine you need exteral inverter in front of RX and TX pin.
+ Otherwise you can software serial routine to communicate the keyboard.
+
+This converter uses software method, you doesn't need any inverter part.
+
+
+Commands From System To Keyboard
+ 0x01 Reset
+ Keyboard responds with following byte sequence:
+ Success: 0xFF 0x04 0x7F
+ Fail: 0x7E 0x01 0x7F
+ 0x02 Bell On
+ 0x03 Bell Off
+ 0x0A Click On
+ 0x0B Click Off
+ 0x0E LED
+ followed by LED status byte:
+ bit: 3 2 1 0
+ LED: CapsLk ScrLk Compose NumLk
+ 0x0F Layout
+ Keyboard responds with 'Layout Response' 0xFE 0xXX
+
+Commands From Keyboard To System
+ 0x7F Idle
+ means no keys pressed.
+ 0xFE Layout Response
+ 0xFF Reset Response(followed by 0x04)
+
+Reference

+ http://kentie.net/article/sunkbd/KBD.pdf
+
+
+Build Firmware
+--------------
+Just use 'make'
+ $ cd sun_usb
+ $ make
+Then, load the binary to MCU with your favorite programmer.
