 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)
+
+CTCSP SHORT TYPE KEYBOARD: http://imgur.com/a/QIv6p
 
-TODO
-----
-AVR UART engine expect positive logic while Sun keyboard signal is inverted serial.
-To use AVR UART engine you need inverter in front of RX and TX pin.
-Otherwise you can software serial routine to communicate the keyboard.

---------
-Target MCU is ATMega32u4 but other USB capable AVR will also work.
-You can use PJRC Teensy as dev board.

+    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.

+            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.

+Build Firmware
+--------------
+Just use 'make'
     $ cd sun_usb
     $ make
-
-And load the binary to MCU with your favorite programmer.
-If you use Teensy you can load with PJRC Teensy Loader tool.
