1. ps2avrU

  2. What is ps2avrU?

  3. Firmware supporting both USB and PS/2

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

  5. Link for projects

  1. 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

  1. 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

  1. 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

  1. 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.

  1. Quick Swap

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

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

  1. 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”

  1. What is ps2avrGB

  2. Supporting ps2avrU + RGB LED control

  3. Supporting all functions BootMapper client provides.

  1. RGB LED

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

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