M0110 Arduino Library for SAMD processors

Library implementing the Apple M0110(A) keyboard protocol to send keystrokes to a Macintosh 128K, Macintosh 512K, or Macintosh Plus. I wrote this library to use a USB keyboard with a Macintosh Plus.

USB to Apple M0110 Keyboard Adapter

Usage

The library needs to be initialized with a data pin and clock pin.

Mac 128k/512k/Plus Keyboard Pinout (Socket on Computer)
.---------.
| 1 2 3 4 | 1 GND
|         | 2 Clock
|         | 3 Data
'---___---' 4 5V

Example:

#include <M0110.h>

#define DAT_PIN 1
#define CLK_PIN 0

M0110 m0110(DAT_PIN, CLK_PIN);

Functions

• begin() allocates memory, configures pins, and enables interrupts
• end() disables interrupts, releases pins, and frees memory
• press(key) presses and holds a single key
• print(characters) sends a string of keystrokes
• println(characters) sends a string of keystrokes followed by a return key
• release(key) releases a single key
• releaseAll() releases all pressed keys
• write(key) presses and releases a single key
