Reactor

Reactor is the firmware generator part of Fusion.

It takes the JSON's exported by the Fusion project and process them in to ready-to-be-downloaded firmware.

Reactor uses the awesome qmk_firmware by Jack Humbert. The firmware is included through a git subtree. To update the firmware, check out updating the firmware.

General process

• Take JSON input
• Generate a .c template file based on the JSON and the liquid template. Name it something unique
• Create a hex file by compiling that c file. Name it something unique too
• Read .hex file and return it

Local development

You can run the tests with be guard - which will watch for changes in ruby files and run whenever they do.

Testing is done in ruby 2.2.2

Updating the firmware

The qmk_firmware is included in this repository as a git subtree. Any changes to qmk_firmware should be made to the qmk_firmware repository not this repository.

To update the subtree from the qmk_firmware repository, pull the updates from qmk_firmware into this repository.

If you don't have the remote and the subtree setup:

1. Add the remote for qmk_firmware

   git remote add -f qmk_firmware git@github.com:jackhumbert/qmk_firmware.git

2. Add the subtree

   git subtree add --prefix lib/firmware qmk_firmware master --squash

If you have the remote and subtree setup:

1. Fetch the updates

   git fetch qmk_firmware master

2. Update the subtree

   git subtree pull --prefix lib/firmware qmk_firmware master --squash

Compiling firmware

Linux

Using the instructions from the teensy loader build environment:

sudo apt-get install gcc-avr binutils-avr avr-libc

Mac OSX

Using homebrew it's easy to compile the firmware:

brew tap osx-cross/avr
brew install avr-libc

Next cd into the appropriate folder of the qmk_firmware, say keyboard/ergodox_ez

cd keyboard/ergodox_ez

Then run make for the default keymap, or

make KEYMAP="yourown"

for your own keymap. This requires a files keymap_yourown.c in the subfolder keymaps. You should end up with a ergodox_ez.hex file, which you can use with the Teensy loader or Teensy GUI
