From 67481f5fd672bac50ae8fa8eb05b6b13ebe25035 Mon Sep 17 00:00:00 2001 From: Jens Arnold Date: Sun, 9 Mar 2008 23:52:59 +0000 Subject: First step towards the iAudio M3 port: Make the 2bit vertically interleaved LCD driver code usable for main or remote. The M3 remote will be treated as the main LCD. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16598 a1c6a512-1295-4272-9138-f99709370657 --- firmware/drivers/lcd-remote-2bit-vi.c | 1235 +-------------------------------- 1 file changed, 6 insertions(+), 1229 deletions(-) (limited to 'firmware/drivers/lcd-remote-2bit-vi.c') diff --git a/firmware/drivers/lcd-remote-2bit-vi.c b/firmware/drivers/lcd-remote-2bit-vi.c index 9f70e95195..d2440a6296 100644 --- a/firmware/drivers/lcd-remote-2bit-vi.c +++ b/firmware/drivers/lcd-remote-2bit-vi.c @@ -18,1235 +18,12 @@ * KIND, either express or implied. * ****************************************************************************/ -#include "config.h" -#include "cpu.h" -#include "lcd.h" -#include "lcd-remote.h" -#include "kernel.h" -#include "thread.h" -#include -#include -#include "memory.h" -#include "file.h" -#include "debug.h" -#include "system.h" -#include "font.h" -#include "rbunicode.h" -#include "bidi.h" -#include "lcd-remote-target.h" -#include "scroll_engine.h" - -/*** globals ***/ - -fb_remote_data lcd_remote_framebuffer[LCD_REMOTE_FBHEIGHT][LCD_REMOTE_FBWIDTH] - IBSS_ATTR;
