IBM 4704 to USB keyboard converter
=======----=======================
This firmware converts IBM 4704 keyboard protocol to USB HID.
Connect Wires
-------------
In case of Teensy2.0(ATMega32U4):
1. Connect Vcc and GND.
2. Connect Clock and Data line.
- Clock is on PD1 and Data on PD2.
3. Optionally you need pull-up register. 1KOhm is OK?
To change pin configuration edit config.h.
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.
