1. ps2avrU

1. What is ps2avrU?

1. Firmware supporting both USB and PS/2

2. Combination of 2 firmwares, “ps2avr”(for ps/2) and “dulcimer”(for USB)

3. Link for projects

• ps2avr : http://ps2avr.sourceforge.net/

• dulcimer : http://www.schatenseite.de/dulcimer.html?L=2

2) Difference between USB and PS/2 interfaces

1. USB

• Supporting 6+1 simulataneous key input

• Supporting normal speed for key repeat

    b. PS/2

• Supporting unlimited simultaneous key input

• Supporting fast speed for key repeat

3) How to change interface

1. Basically it changes automatically

2. If you want to change manually

• to USB : While pressing "U" key, connect the keyboard to USB port.

• to PS/2 : While pressing "P" key, connect the keyboard to PS/2 port.

    c. If you want to reset : While pressing "U"+ "P", connect the keyboard to port

4) Interface Signal

1. Flashing count of CapsLock/NumLock LED

• 1 time : recognizing PS/2

• No flashing : recognizing USB

• Continuous flashing : in the process of recognizing

5) Basic functions

1. Supproting Full LED

2. Providing interface to change LED mode : While pressing “ESC”, press “Caps Lock” (or FN + caps lock) for specfic times

• 1 time : LED off

• 2 times : Fading

• 3 times : LED on

• 4 times and then any key down :  Getting brighter

• 5 times and then any key down : Getting darker

     c. Setting full LED brightness using macro

• KEY_LED_UP : getting brighter

• KEY_LED_DOWN : getting darker

     d. Mapping keys for brightness

• A.87 and MX-mini series : FN + - / FN + =

• Thumb series : FN + R Alt/ FN + R Ctrl

    e. 4 Layer Key Map

• 1 : normal

• 2 :  FN

• 3 :  FN2/FN3

    f.  Scroll Lock LED signal

• There is no special signal for Scroll Lock LED. But you can tell by seeing Caps Lock LED flashing when it turns on or off(1 tiem for off, 2 times for on).

• One of Firmware files named “SL_apart” shows Scroll Lock LED in MCU PD6 pin.

• Sleep Mode : When system ends, keyboard enter sleep mode turning LED off when connected through USB.

8) Quick Swap

1. “Swap” means altering between “alt” and “GUI”

2. Press “alt” + “GUI” together for 5 seconds.

9) Special Keys

1. How to use hardware menu

• Open a text editting program such as NotePad.

• Press Left Ctrl + alt + shift + Right shift(total 4keys) for 5 seconds and then you’ll see the menus

• Here are the messages.

hello

select mode

1:keymapper

2:macro

3:lazy fn : on

4:fn2/3 led : sl

5:esc to ~ : off

7:exit

9:boot mapper

>>

b. Lock Key/Win Key

• Lock Key : prevents input form all the keys.(toggle)

• Lock Win : block left/right window key press.(toggle)

c. Lazy FN/FN2

• If you set lazy FN  option  on, you can’t change layer.

• This option can be set in the hardware key mapper menu.

d. dual action key

• This action is handling a several of key functions.

• You can add this functions to the keys like FN, FN2, Ctrl, alt, shift.   

e. how dual action key acts

• It gives the delay of 0.5 seconds.

• So you have to wait for a while to get combination key

• If you conbine it to other keys, it acts without delay.

• If you want to change the language with only one key(Lang key), you have to press down and up in  0.5 second.

f. Shift + Esc = ~

• In mini keyboard, entering “~” is difficult. So you can do that with “Shift + ESC” key.

• In Key Mapper menu, change “esc to ~” option to “on”  

2. ps2avrGB

1. What is ps2avrGB

1. Supporting ps2avrU + RGB LED control

2. Supporting all functions BootMapper client provides.

1. Provides the interface to change RGB LED color by using bootMapper client.

2. Mode Change : ESC + SHIFT + Caps lock or  LED MODE2

3. Changing of RGB key event mode : ESC + Ctrl + Capslock or Ctrl + LED_MODE2

4. Setting brightness : SHIFT+KEY_LED_UP, SHIFT+KEY_LED_DOWN (The brighter RGB LED, the darker full LED)

5. Basic Key Mapping on the keyboard with F keys

• LED MODE : FN+Caps lock

• KEY_LED_UP : FN + =

• KEY_LED_DOWN : FN + -

    f. Basic Key Mapping on the keyboard without F keys

• KEY_LED_UP : FN + H

• KEY_LED_DOWN : FN + G
