IBM 4704 to USB keyboard converter
This firmware converts IBM 4704 keyboard protocol to USB HID.
4704 Connector
Keyboard Plug from front
DSUB-9
-------------
\ N 2 3 4 5 /
\ N N N N /
---------
2 GND
3 VCC 5V
4 DATA
5 CLOCK
N No connection/No pin.
Connection
In case of using ATMega32U4(Teensy2.0):
- Supply power with VCC and GND.
- Connect CLOCK to PD1 and DATA to PD2. You can change pin with config.h.
- Optionally you may need pull-up register. 1KOhm probably work.
Build Firmware
Just run make:
$ make
To select keymap:
$ make KEYMAP=[plain|...]
Keymap
Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named keymap_<name>.c and see keymap document(you can find in top README.md) and existent keymap files.
