IBM 4704 to USB keyboard converter | |||||
================================== | |||||
This firmware converts IBM 4704 keyboard protocol to USB HID. | |||||
Keyboard initialization process takes a few seconds at start up. During that you will hear buzzer from the keyboard. **You need to plug USB cable after hooking up your keyboard to the converter.** | |||||
4704 Connector | |||||
-------------- | |||||
Keyboard Plug from front: | |||||

2 GND | |||||
3 VCC 5V | |||||
4 DATA | |||||
5 CLOCK | |||||
N No connection/No pin. | |||||
Connection | |||||
---------- | |||||
In case of using ATMega32U4(Teensy2.0): | |||||
1. Supply power with VCC and GND. | |||||
2. Connect CLOCK to PD1 and DATA to PD0. You can change pin with config.h. | |||||
3. 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. |

4704 Keyboard Protocol | |||||
====================== | |||||
On powering up the keyboard sends keyboard id; A3h for 6019284(62-key), for example. | |||||
After that firmware enters FC command mode and waits for parameter data from host | |||||
so that it doesn't send any scancode until you send 'FF'(End of FC command). | |||||
