keyboard.device — Keyboard Input

Overview

keyboard.device provides raw keycode events from the keyboard controller (8520 CIA-A). Normally used indirectly via input.device, but can be accessed directly for keymap-independent scanning.

Keycodes

Amiga keycodes are 7-bit values (0–127). Bit 7 indicates key-up:

Code	Key	Code	Key
`$00`	` (backtick)	`$40`	Space
`$01`–`$0A`	1–0	`$41`	Backspace
`$10`–`$19`	Q–P	`$42`	Tab
`$20`–`$28`	A–L	`$43`	Enter (keypad)
`$31`–`$39`	Z–/	`$44`	Return
`$45`	Escape	`$46`	Delete
`$4C`	Cursor Up	`$4D`	Cursor Down
`$4E`	Cursor Right	`$4F`	Cursor Left
`$50`–`$59`	F1–F10	`$5F`	Help
`$60`	Left Shift	`$61`	Right Shift
`$62`	Caps Lock	`$63`	Control
`$64`	Left Alt	`$65`	Right Alt
`$66`	Left Amiga	`$67`	Right Amiga

Commands

Code	Constant	Description
2	`CMD_READ`	Read raw keycodes
5	`CMD_CLEAR`	Clear keyboard buffer
9	`KBD_READMATRIX`	Read full key matrix state
10	`KBD_ADDRESETHANDLER`	Add Ctrl-Amiga-Amiga handler
11	`KBD_REMRESETHANDLER`	Remove reset handler
12	`KBD_RESETHANDLERDONE`	Acknowledge reset handler completion
