From f64f589d2efeb2749314bb9f91523b4555ded2d5 Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Fri, 10 Nov 2006 00:02:28 +0000 Subject: H100/120: Split lcd driver into pixel format and device specific parts. Adjustment of contrast range to just a little less than white to a little more than black. Really only had to reset minimum. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11487 a1c6a512-1295-4272-9138-f99709370657 --- firmware/target/coldfire/iriver/h100/lcd-h100.c | 1098 +---------------------- 1 file changed, 14 insertions(+), 1084 deletions(-) (limited to 'firmware/target/coldfire/iriver') diff --git a/firmware/target/coldfire/iriver/h100/lcd-h100.c b/firmware/target/coldfire/iriver/h100/lcd-h100.c index 9ed63661a0..9d2f7dac6b 100644 --- a/firmware/target/coldfire/iriver/h100/lcd-h100.c +++ b/firmware/target/coldfire/iriver/h100/lcd-h100.c @@ -18,18 +18,9 @@ ****************************************************************************/ #include "config.h" -#include "cpu.h" -#include "lcd.h" -#include "kernel.h" -#include "thread.h" -#include -#include -#include "file.h" -#include "debug.h" #include "system.h" -#include "font.h" -#include "rbunicode.h" -#include "bidi.h" +#include "kernel.h" +#include "lcd.h" /*** definitions ***/ @@ -59,58 +50,23 @@ #define LCD_CNTL_COLUMN 0x13 #define LCD_CNTL_DATA_WRITE 0x1d -#define SCROLLABLE_LINES 26 - -/*** globals ***/ - -fb_data lcd_framebuffer[LCD_HEIGHT/4][LCD_WIDTH] IBSS_ATTR;
