From d2ff66a985b938e87fffe55c1d9f1dc55e356f91 Mon Sep 17 00:00:00 2001 From: Jack Humbert Date: Wed, 23 Aug 2017 22:29:07 -0400 Subject: Creates a layouts/ folder for keymaps shared between keyboards (#1609) * include variables and .h files as pp directives * start layout compilation * split ergodoxes up * don't compile all layouts for everything * might seg fault * reset layouts variable * actually reset layouts * include rules.mk instead * remove includes from rules.mk * update variable setting * load visualizer from path * adds some more examples * adds more layouts * more boards added * more boards added * adds documentation for layouts * use lowercase names for LAYOUT_ * add layout.json files for each layout * add community folder, default keymaps for layouts * touch-up default layouts * touch-up layouts, some keyboard rules.mk * update documentation for layouts * fix up serial/i2c switches --- keyboards/ergodox_ez/matrix.c | 394 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 394 insertions(+) create mode 100644 keyboards/ergodox_ez/matrix.c (limited to 'keyboards/ergodox_ez/matrix.c') diff --git a/keyboards/ergodox_ez/matrix.c b/keyboards/ergodox_ez/matrix.c new file mode 100644 index 000000000..b743cf0d6 --- /dev/null +++ b/keyboards/ergodox_ez/matrix.c @@ -0,0 +1,394 @@ +/* + +Note for ErgoDox EZ customizers: Here be dragons! +This is not a file you want to be messing with. +All of the interesting stuff for you is under keymaps/ :) +Love, Erez + +Copyright 2013 Oleg Kostyuk + +This program is free software: you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation, either version 2 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
