From 8df1a7e29abd51cc455844a9633e1cc5e057065f Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Wed, 29 Oct 2008 01:42:03 +0000 Subject: e200v2: implement the backlight handling (copy/paste from the c200v1/e200v1 code - this should probably be unified, along with other upcoming v2 code), plus clean up the lcd init by calling lcd_init() directly in the bootloader, instead of lcd_init_device(). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18910 a1c6a512-1295-4272-9138-f99709370657 --- firmware/SOURCES | 1 + firmware/export/config-e200v2.h | 4 +- .../target/arm/as3525/sansa-clip/lcd-ssd1303.c | 2 + .../arm/as3525/sansa-e200v2/backlight-e200v2.c | 71 ++++++++++++++++++++++ .../arm/as3525/sansa-e200v2/backlight-target.h | 21 +++---- 5 files changed, 85 insertions(+), 14 deletions(-) create mode 100644 firmware/target/arm/as3525/sansa-e200v2/backlight-e200v2.c (limited to 'firmware') diff --git a/firmware/SOURCES b/firmware/SOURCES index 7a93d058b4..f2f8526494 100644 --- a/firmware/SOURCES +++ b/firmware/SOURCES @@ -1046,6 +1046,7 @@ target/arm/as3525/as3525-codec.c #ifndef SIMULATOR target/arm/as3525/sansa-e200v2/lcd-e200v2.c target/arm/as3525/sansa-e200v2/button-e200v2.c +target/arm/as3525/sansa-e200v2/backlight-e200v2.c target/arm/as3525/as3525-codec.c #endif /* !SIMULATOR */ #endif /* SANSA_E200V2 */ diff --git a/firmware/export/config-e200v2.h b/firmware/export/config-e200v2.h index 5b051f2a89..0dc87d4123 100644 --- a/firmware/export/config-e200v2.h +++ b/firmware/export/config-e200v2.h @@ -47,6 +47,7 @@ #define LCD_DEPTH 16 /* 65536 colours */ #define LCD_PIXELFORMAT RGB565 /* rgb565 */ +#ifndef BOOTLOADER /* define this if you have LCD enable function */ #define HAVE_LCD_ENABLE @@ -54,6 +55,7 @@ should be defined as well. */ #define HAVE_LCD_SLEEP #define HAVE_LCD_SLEEP_SETTING +#endif /* define this if you can flip your LCD */ #define HAVE_LCD_FLIP @@ -165,7 +167,7 @@ #define CONFIG_USBOTG USBOTG_AS3525 /* enable these for the experimental usb stack */ -#define HAVE_USBSTACK +//#define HAVE_USBSTACK #define USB_VENDOR_ID 0x0781 #define USB_PRODUCT_ID 0x7423 diff --git a/firmware/target/arm/as3525/sansa-clip/lcd-ssd1303.c b/firmware/target/arm/as3525/sansa-clip/lcd-ssd1303.c index 4ae13a5fcc..ed4bcc7be9 100644 --- a/firmware/target/arm/as3525/sansa-clip/lcd-ssd1303.c +++ b/firmware/target/arm/as3525/sansa-clip/lcd-ssd1303.c @@ -228,6 +228,8 @@ void lcd_init_device(void) lcd_write_data(p_bytes, LCD_FULLSCREEN /* overscan */);
