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. |
