+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)

+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)
+

+
+
+Build Firmware
+--------------
+Just use 'make'
+    $ cd sun_usb
+    $ make
+Then, load the binary to MCU with your favorite programmer.
