PS/2 to USB keyboard converter
==============================
This firmware converts PS/2 keyboard protocol to USB and for now supports only Scan Code Set 2.
+This will works on USB AVR(ATMega32U4, AT90USB) or V-USB.
Features
--------
Mouse keys
You can emulates mouse move and button click using keyboard.
-
System/Media control
You can sends Power event, Volume down/up and Mute.
-
USB NKRO(actually 120KRO+8Modifiers)
You can tolggles NKRO feature.
-
Keymap customization
You can customize keymaps easily by editing source code. See keymap.c.
+PS/2 signal handling implementations
+------------------------------------
+Following three methods are used to implement PS/2 signal handling.
+a. Simple and stupid wait & read loop(intensive use of cycles)
+ This is implemented with (expected) portable C code for reference. See ps2.c.
+b. Interrupt driven
+ See ps2_intr.c
+c. Using USART hardware module(no cycle needed)
+ This uses AVR USART function to recevie PS/2 signal and be used in V-USB converter.
+ See ps2_usart.c.
+
+
Build Converter
---------------
-0. Connect PS/2 keyboard into Teensy with 4 lines(Vcc, GND, Data, Clock).
- By default Clock is on PF0 and Data on PF1.
- You can change this pin configuration by editing config_pjrc.h.
- In this photo Vcc is yellow, GND is green, Data is red and Clock is black.

+For c. USART implementation:
+ In case of Teensny(ATMega32u4) CLock is on PD2 and Data on PD5.
Build Frimware
--------------
1. Edit Makefile for build options and MCU setting.
- Use 'atmega32u4' for Teensy 2.0 or 'at90usb1286' for Teensy++ 2.0.
+ Use 'atmega32u4' for Teensy 2.0 or 'at90usb1286' for Teensy++ 2.0.
2. make
- Just type 'make' in a terminal.
+ Just type 'make' in a terminal.
+ Use '-f Makefile.pjrc_intr' option to use b. Interrupt.
+ Use '-f Makefile.pjrc_usart' option to use c. USART.
+ Use '-f Makefile.vusb' option to build V-USB converter.
3. program with Teensy Loader.
