Replacable USB Controller for Apple IIgs/Standard(M0116) | |||||
JeffreySung([email protected]) | |||||
=============================== | |||||
Feature | |||||
------- | |||||
- Replaceable keyboard controller for Apple IIgs(A9M0330)/Standard(M0116) | |||||
- Teensy++ 2.0 required | |||||
- Some signal bypass required | |||||
- ADB keyboard doesn't use matrix for modifier keys. With virtual row for modifier keys, | |||||
these keys are merged into key matrix using virtual row. | |||||
History | |||||
======= | |||||
- 2012.09.17 First Release | |||||
- 2012.09.17 CapsLock support | |||||
- 2012.09.19 Power button added | |||||
Build | |||||
===== | |||||
0. Just Type "Make" and return. | |||||
Hardware | |||||
======== | |||||
PJRC Teensy | |||||
----------- | |||||
0. The following ports should not be connected to board. | |||||
From top view of Teensy++, from GND and counter clock wise. | |||||
-7,26(in keyboard PCB, these pins are VDD,GND) | |||||
-30,31(in Teensy++, these pins are Ref,GND respectively) | |||||
-5,6(D2,D3 for bluetooth in future) | |||||
1. Bypass #31 pin(from board) to E4(Teensy) | |||||
2. Bypass #30 pin(from board) to F2(Teensy) | |||||
3. Bypass #6 pin(from board) to A0(Teensy) | |||||
4. Refer doc directory | |||||
To Do | |||||
===== | |||||
0. When DEBOUNCE defined, there is a errors. | |||||
1. Layer Change by toggling Clear Key | |||||
2. Eject Key add. (following files should be modified.) | |||||
common/usb_keycodes.h | |||||
common/keyboard.c | |||||
3. Use bluetooth | |||||
