+Pinouts

+ Female socket from the front
+

+
+
+Commands
+--------
+ ADB command is 1byte and consists of 4bit-address, 2bit-command
+ type and 2bit-register. The commands are always sent by Host.
+
+ Command format:
+ 7 6 5 4 3 2 1 0
+ | | | |------------ address
+ | |-------- command type
+ | |---- register
+
+ bits commands
+ ------------------------------------------------------
+ - - - - 0 0 0 0 Send Request(reset all devices)
+ A A A A 0 0 0 1 Flush(reset a device)
+ - - - - 0 0 1 0 Reserved
+ - - - - 0 0 1 1 Reserved
+ - - - - 0 1 - - Reserved
+ A A A A 1 0 R R Listen(write to a device)
+ A A A A 1 1 R R Talk(read from a device)
+
+ The command to read keycodes from keyboard is 0x2C which
+ consist of keyboard address 2 and Talk against register 0.
+
+ Address:
+ 2: keyboard
+ 3: mice
+
+ Registers:
+ 0: application(keyobard/mice use to store its data.)
+ 1: application
+ 2: application
+ 3: status and command
+
+
+Communication
+-------------
+ This is a minimum information for keyboard communication.
+ See "Resources" for detail.

+ [from Apple IIgs Hardware Reference Second Edition]
+
+ Criterion for bit0/1:
+ After 55us if line is low/high then bit is 0/1.
+
+ Attention & start bit:
+ Host asserts low in 560-1040us then places start bit(1).
+
+ Tlt(Stop to Start):
+ Bus stays high in 140-260us then device places start bit(1).
+
+ Global reset:
+ Host asserts low in 2.8-5.2ms. All devices are forced to reset.
+
+ Send request from device(Srq):
+ Device can request to send at commad(Global only?) stop bit.
+ keep low for 300us to request.
+
+
+Keyboard data(register0)
+ This 16bit data can contains 2 keycodes and 2 released flags.
+ First keycode is palced in upper nibble. When one keyocode is sent,
+ lower nibble is 0xFF.
+ Release flag is 1 when key is released.
+
+ 15 14 . . . . . 8 7 6 . . . . . 0
+ | |keycode1 | |keycode2
+ |released(1) |released(1)
+
+ Keycodes:
+ Scancode consists of 7bit keycode and 1bit release flag.
+ Device can send two keycodes at once. If just one keycode is sent
+ keycode1 contains it and keyocode2 is 0xFF.
+
+ Power switch:
+ You can read the state from PSW line(active low) however
+ the switch has a special scancode 0x7F7F, so you can
+ also read from Data line. It uses 0xFFFF for release scancode.

+=============================
+
+This firmware converts ADB keyboard protocol to USB.
+
+Build
+-----
+0. Connect ADB keyboard to Teensy by 3 lines(Vcc, GND, Data).
+ PSW line is optional. See ADB.txt for details.
+1. Define following macros for ADB connection in config.h:
+ ADB_PORT
+ ADB_PIN
+ ADB_DDR
+ ADB_DATA_BIT
+ ADB_PSW_BIT
+2. make
+3. program Teensy.
