[apple] 현대 MacBook Pro에서 원본 Mac Plus 또는 Mac 128k 마우스를 사용할 방법이 있습니까?

고대 스레드 -하지만 같은 생각을 찾고 있었어.

USB 장치에서 사용할 구적 변조를 감추기 위해 HID 기능이있는 arduino / teensy를 사용할 수 있습니다.

DE9 핀아웃 (아래 코드의 arduino 핀 포함)은 다음과 같습니다.

DB9     Pro Micro
    1       GND
    2       VCC
    3       GND
    4       D0      (pin 3)
    5       D1      (pin 2)
    6       -       (not connected)
    7       B3      (pin 14)
    8       D3      (pin TXO)
    9       D2      (pin RXI)

GuilleAcoustic의 원래 샘플 코드 중 Johan Berglund가 수정 한 샘플 코드는 다음과 같습니다.

   Modified for use with Apple M0100 mouse
   By Johan Berglund, 2015-08-10

   Changes in code:
   - Internal pullup set for pin 14 (B3)
   - State check for right and middle buttons commented out

   Connection to DB9:
