# jj40
|
|
|
|
|
|
|
|
A compact 40% (12x4) ortholinear keyboard kit made and KPRepublic on AliExpress.
|
|
|
|
Keyboard Maintainer: [QMK Community](https://github.com/qmk)
|
|
Hardware Supported: Atmega32A
|
|
Hardware Availability: [AliExpress](https://www.aliexpress.com/store/product/jj40-Custom-Mechanical-Keyboard-40-PCB-programmed-40-planck-layouts-bface-firmware-gh40/3034003_32828781103.html)
|
|
|
|
Make example for this keyboard (after setting up your build environment):
|
|
|
|
make jj40:default:program
|
|
|
|
See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
|
|
|
|
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.
|
|
|
|
In addition you may need the AVR toolchain and `bootloadHID` ([GitHub repo](https://github.com/whiteneon/bootloadHID)) for flashing:
|
|
|
|
For macOS:
|
|
```
|
|
$ brew cask install crosspack-avr
|
|
$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
|
|
```
|
|
|
|
For Linux:
|
|
```
|
|
$ sudo apt install libusb-dev
|
|
$ wget https://www.obdev.at/downloads/vusb/bootloadHID.2012-12-08.tar.gz
|
|
$ tar -xzf bootloadHID.2012-12-08.tar.gz
|
|
$ cd bootloadHID.2012-12-08/commandline
|
|
$ make
|
|
$ sudo cp bootloadHID /usr/bin
|
|
```
|
|
|
|
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
|
|
```
|
|
|
|
If you prefer (or are having issues with a `program` flash), you can just build it (`make jj40:<keymap-name>` and flash the firmware (`.hex` file) directly with
|
|
`bootloadHID` if you boot the board while holding down `Backspace` (`Top Right Key`) to keep it
|
|
in the bootloader:
|
|
|
|
```
|
|
$ make jj40
|
|
$ bootloadHID -r jj40_default.hex
|
|
```
|
|
|
|
For Windows 10:
|
|
Windows sometimes doesn't recognize the jj40. The easiest way of flashing a new layout is probably using [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
|
|
1. Go to Windows Device Manager and find the keyboard (plug it in while holding down `Backspace` (`Top Right Key`)). It can be found under Human Interface Devices or under Keyboards.
|
|
2. Go to properties and the Details tab to find the hardware ID. You want the VID and the PID (code after the underscore). Plug them into HIDBootFlash and hit Find Device.
|
|
3. Use `make jj40:<keymap-name>` to generate the .hex file in the qmk basis folder. Select the .hex file in HIDBootFlash and press Flash Device.
|
|
|
|
|
|
## Troubleshooting
|
|
|
|
1. Try plugging the board in while pressing `Backspace` (`Top Right 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.
|
|
3. If you get an error such as "Resource Unavailable" when attemting to flash
|
|
on Linux, you may want to compile and run `tools/usb_detach.c`. See `tools/README.md`
|
|
for more info.
