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


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”

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.

  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
