-Sun to USB keyboard protocol converter
-======================================
-Target MCU is ATMega32u4 but other USB capable AVR will also work.
-
-This converter will work with Sun Type 2-5 Keyboards.
-
-
-Tested on:
-Sun Type 3 Keyboard: http://blog.daveastels.com.s3-website-us-west-2.amazonaws.com/2014/12/27/type-3-keyboard.html
-CTCSP SHORT TYPE KEYBOARD(Type 5): http://imgur.com/a/QIv6p
-
-
-Keymap of Type 3(keymap_sun3.c) were impoted from dastels's repository.

-
-Protocol
---------
-Signal: 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 external 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.
-
-
-Sun commands
-------------
-You can send Sun protocol commands with TMK `Magic` key combo. By default `Magic` key is `LShift` + `RShift`, `LAlt` + `RAlt' or `LMeta` + `RMeta`.
-https://github.com/tmk/tmk_keyboard#magic-commands
-
-Following Sun specific commands are available. For example, to send 'Bell On' you can press `LShift` + `RShift` + `Up` keys simultaneously.
