why would you want to generate the hex file using the output of the configurator but not have the configurator generate the hex? if you want to build the firmware locally you can checkout the tmk repo on my github (evangs). There is also a QMK port of the firmware as well.
Haha, yeah I can see why it seems a bit weird but this is the process leading up to the question:
1. Finish the board, make some quick layout in the online configurator and flash it just to try it out.
2. Want to make some changes to the layout, realize I have to input everything again from scratch since I cannot load the current config from the hexfile I already have.
3. Realize I can actually load the config from the text format.
4. Save the text format locally so I don't have to start from scratch when making changes.
5. Realize it would be sweet to not take the detour to online configurator to create the hexfile.
So would the easiest way then be to use the tmk repo? Is that what the online conf is using on the backend?
Thanks!
