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.
