From 13bb6b4b7fdd2b3e419d0f89c93fb980b00eeb9b Mon Sep 17 00:00:00 2001 From: Jack Humbert Date: Thu, 23 Jun 2016 22:18:20 -0400 Subject: Backlight abstraction and other changes (#439) * redoes matrix pins, abstracts backlight code for B5,6,7 * slimming down keyboard stuff, backlight breathing implemented * don't call backlight init when no pin * cleans up user/kb/quantum calls, keyboard files * fix pvc atomic * replaces CHANNEL with correct var in breathing * removes .hexs, updates readmes, updates template * cleans-up clueboards, readmes to lowercase * updates readme --- keyboards/atomic/atomic.c | 312 +--------------------------------------------- 1 file changed, 1 insertion(+), 311 deletions(-) (limited to 'keyboards/atomic/atomic.c') diff --git a/keyboards/atomic/atomic.c b/keyboards/atomic/atomic.c index fa218a48f3..6f393315ee 100644 --- a/keyboards/atomic/atomic.c +++ b/keyboards/atomic/atomic.c @@ -1,26 +1,5 @@ #include "atomic.h" -__attribute__ ((weak)) -void matrix_init_user(void) { - // leave this function blank - it can be defined in a keymap file -};
