1) What is ps2avrU?
a. Firmware supporting both USB and PS/2
b. Combination of 2 firmwares, “ps2avr”(for ps/2) and “dulcimer”(for USB)
c. Link for projects
2) Difference between USB and PS/2 interfaces
- Supporting 6+1 simulataneous key input
- Supporting normal speed for key repeat
- Supporting unlimited simultaneous key input
- Supporting fast speed for key repeat
3) How to change interface
a. Basically it changes automatically
b. If you want to change it 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
a. You can tell by 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
a. Supporting Full LED
b. Providing interface to change LED mode : While pressing “ESC”, press “Caps Lock” for specific times

- 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
c. Mapping keys for brightness
- A.87 and MX-mini series : FN + – / FN + =
- Thumb series : FN + R Alt/ FN + R Ctrl
d. 4-Layer Key Map
- 1 : Normal
- 2 : FN
- 3 : FN2/FN3
e. 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
a. “Swap” means altering between “alt” and “GUI”
b. Press “alt” + “GUI” together for 5 seconds.
9) Special Keys
<Lock Key/Win Key>
- Lock Key : prevents input form all the keys.(toggle)
- Lock Win : block left/right window key press.(toggle)
- If you set lazy FN option on, you can’t change layer.
- This option can be set in the hardware key mapper menu.
<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”
10) Dual action key
- This action is triggered by combining a several key functions.
- If you don’t combine other keys, it is act as a normal function key like Lang key.
- You can add this functions to the keys like FN, FN2, Ctrl, alt, shift.
- For exmaple, if you press other key while pressing the key “KEY_FN_HANGLE” , then it is act as “FN” key.
But solely this key act as Lang(hangle<->eng) key.
- Dual Action key list
11) how dual action key acts
- You have to wait 0.5 second after pressing it to make it act as Dual Key.
- If you combine other keys, it act as Dual key without 0.5 second waiting.
- If you want to change the language with only one key(Lang key), you have to press down and up in 0.5 second.
1) What is ps2avrGB
a. Supporting ps2avrU + RGB LED control
b. Supporting all functions BootMapper client provides.
2) RGB LED
a. Provides the interface to change RGB LED color by using bootMapper client.
b. Mode Change : ESC + SHIFT + CapsLock or LED MODE2
c. Changing of RGB key event mode : ESC + Ctrl + CapsLock or Ctrl + LED_MODE2
d. Setting brightness : SHIFT+KEY_LED_UP, SHIFT+KEY_LED_DOWN (The brighter RGB LED, the darker full LED)
Basic Key Mapping on the keyboard with F keys
- LED MODE : FN+Caps lock
- KEY_LED_UP : FN + =
- KEY_LED_DOWN : FN + –
e. Basic Key Mapping on the keyboard without F keys
- KEY_LED_UP : FN + H
- KEY_LED_DOWN : FN + G
