PS/2 to USB keyboard converter
==============================
This firmware converts PS/2 keyboard protocol to USB.(It supports Scan Code Set 2.)
Connect Wires
-------------
In case of Teensy2.0(ATMega32U4):
1. Connect **Vcc** and **GND**.
2. Connect **Clock** and **Data** line.
- **Interrupt**: **Clock** is on `PD1` and **Data** on `PD0`.(Recommended. Soarer's converter compatible)
- **Busywait**: **Clock** is on `PD1` and **Data** on `PD0`.
- **USART**: **Clock** is on `PD5` and **Data** on `PD2`.
3. Optionally you need pull-up resistor. 1K-10K Ohm is OK.
To change pin configuration edit **config.h** and **Makefile**.
Build Firmware
--------------
For **PJRC Teensy** just run `make`:
$ make clean
$ make
To select keymap:
$ make clean
$ make KEYMAP=[plain|jis|spacefn|...]
After that you will find HEX file `ps2_usb_lufa.hex` in current directory.
- For **TMK converter Rev.1** use `make -f Makefile.tmk_rev1` instead of `make` and HEX file is `ps2_usb_tmk_rev1.hex`.
- For **TMK converter Rev.2** use `make -f Makefile.tmk_rev2` instead of `make` and HEX file is `ps2_usb_tmk_rev2.hex`.
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 README.md of top directory) and existent keymap files.
PS/2 signal handling implementations
------------------------------------
Following three methods can be used to implement PS/2 signal handling.
### Simple and stupid busy-wait(ps2_busywait.c)
This is expected to implemented with portable C code for reference.
### Interrupt driven(ps2_interrupt.c)
Uses pin interrupt to detect falling edge of clock line.
### USART hardware module(ps2_usart.c)
Uses AVR USART engine to receive PS/2 signal.
To select method edit Makefile.
V-USB Support
-------------
With V-USB you can use this converter on ATmega(168/328) but it doesn't support NKRO at this time.
Circuit:
