NerD keyboard firmware
|
||||
========================
|
||||
|
||||
Korean Keyboard designed by GON.
|
||||
|
||||
*Note that this is not the official firmware*
|
||||
|
||||
|
||||
Hardware revision
|
||||
-----------------
|
||||
|
||||
This firmware was developed and tested for NerD pcb version 1.61 and 2.0.
|
||||
|
||||
|
||||
Supported features
|
||||
------------------
|
||||
|
||||
* All layout options are supported
|
||||
* All leds are supported
|
||||
|
||||
|
||||
Changing Bootloader
|
||||
-------------------
|
||||
|
||||
You can't simply just upload this firmware to a new NerD board because the original
|
||||
bootloader won't accept DFU connections.
|
||||
|
||||
You can change the bootloader of the keyboard with an ISP programmer of your choice.
|
||||
The bootloader pins are easy to access on the NerD pcb.
|
||||
|
||||
*Be aware that after changing the bootloader the official configuration software
|
||||
won't work anymore and you'll lose your warrenty. GON won't provide any support for this firmware.*
|
||||
|
||||
|
||||
Build
|
||||
-----
|
||||
|
||||
Move to this directory then just run `make`.
|
||||
|
||||
|
||||
Jump to Bootloader
|
||||
------------------
|
||||
|
||||
You can jump to bootloader by software if you have a macro defined for this in your keymap. The
|
||||
default command is (LSFT+RSFT+PAUS) to access the bootloader by software jump.
