DIY compact keyboard by Massdrop.
Move to this directory then just run make like:
$ git submodule update tmk_core/
$ make
Use make -f Makefile.pjrc if you want to use PJRC stack but I find no reason to do so now.
Press the button on the back of the keyboard and execute:
$ ./flash.sh
And replug your keyboard.
Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named keymap_<name>.c and see keymap document(you can find in top README.md) and existent keymap files.
To build firmware binary hex file with a certain keymap just do make with KEYMAP option like:
$ make KEYMAP=<name>
keymap_default.c is a keymap designed by Julien Pecqueur.
keymap_spacefn.c is a SpaceFn keymap designed by Julien Pecqueur.
