ps2avrGB keyboard firmware
|
|
==========================
|
|
|
|
This is a port of the QMK firmware for boards that are based on the
|
|
ps2avrGB firmware, like the [ps2avrGB
|
|
keyboard](https://www.keyclack.com/product/gb-ps2avrgb/) or the ones sold
|
|
by [Winkeyless](http://winkeyless.kr/product/ps2avrgb-parts/).
|
|
|
|
Note that this is a complete replacement for the firmware, so you won't be
|
|
using Bootmapper Client to change any keyboard settings, since not all the
|
|
USB report options are supported.
|
|
|
|
## Supported Boards
|
|
|
|
Only the [B.mini X2](http://winkeyless.kr/product/b-mini-x2-pcb/) has been
|
|
tested so far (since it's the only one I own). But other boards that use
|
|
the ps2avrGB firmware should work as well.
|
|
|
|
## Installing
|
|
|
|
First, install the requirements. These commands are for OSX, but all you
|
|
need is the AVR toolchain and `bootloadHID` for flashing:
|
|
|
|
```
|
|
$ brew cask install crosspack-avr
|
|
$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
|
|
```
|
|
|
|
In order to use the `./program` script, which can reboot the board into
|
|
the bootloader, you'll need Python 2 with PyUSB installed:
|
|
|
|
```
|
|
$ pip install pyusb
|
|
```
|
|
|
|
Then, with the keyboard plugged in, simply run this command from the
|
|
`qmk_firmware` directory:
|
|
|
|
```
|
|
$ make ps2avrGB:program
|
|
```
|
|
|
|
If you prefer, you can just build it and flash the firmware directly with
|
|
`bootloadHID` if you boot the board while holding down `L_Ctrl` to keep it
|
|
in the bootloader:
|
|
|
|
```
|
|
$ make ps2avrGB
|
|
$ bootloadHID -r ps2avrGB_default.hex
|
|
```
|
|
|
|
## Setting the board to bootloader mode
|
|
|
|
If you're lucky, the programming script does this automagically for you. If
|
|
however this doesn't work for you, you need to enter the bootloader mode manually
|
|
by plugging the keyboard in while holding the bootloader key. If you did this
|
|
correctly the LEDs will blink and you'll be able to flash your firmware.
|
|
|
|
The bootloader key is the top left key of your matrix. For a standard board
|
|
from winkeyless.kr this is `L_Ctrl`, but for some custom boards running ps2avrGB
|
|
this might be different. For the Pearl it's `Esc`, for a b.fake it is `q`. If
|
|
you're unsure you should be able to see the key in the bootmapper client.
|
|
|
|
|
|
## Troubleshooting
|
|
|
|
From my experience, it's really hard to brick these boards. But these
|
|
tricks have been useful when it got stuck in a weird scenario.
|
|
|
|
1. Try plugging the board in while holding the bootloader key. This will force
|
|
it to boot only the bootloader without loading the firmware. Once this is
|
|
done, just reflash the board with the original firmware.
|
|
2. Sometimes USB hubs can act weird, so try connecting the board directly
|
|
to your computer or plugging/unplugging the USB hub.
