From 08c41d42bb699a1be99c9696b4d4fb7b40e8723a Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Sun, 19 Oct 2008 14:11:01 +0000 Subject: Add e200v2 and m200v2 targets. Move the telechips lcd-ssd1815.c (currently used by Logik DAX and m200v1 ports) driver up in the target tree and share with the m200v2 - as2525 parts contributed by Rafael Carre. Includes the start (but is still very incomplete) of an LCD driver for the e200v2. m200v2 is not yet fully supported by mkamsboot - that will come soon. Also some minor cleanups for the Clip. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18836 a1c6a512-1295-4272-9138-f99709370657 --- .../target/arm/as3525/sansa-e200v2/adc-target.h | 24 ++ .../arm/as3525/sansa-e200v2/backlight-target.h | 37 ++ .../target/arm/as3525/sansa-e200v2/button-e200v2.c | 98 ++++++ .../target/arm/as3525/sansa-e200v2/button-target.h | 60 ++++ .../target/arm/as3525/sansa-e200v2/lcd-e200v2.c | 385 +++++++++++++++++++++ .../target/arm/as3525/sansa-e200v2/system-target.h | 28 ++ .../target/arm/as3525/sansa-e200v2/timer-target.h | 38 ++ .../target/arm/as3525/sansa-m200v2/adc-target.h | 24 ++ .../arm/as3525/sansa-m200v2/backlight-target.h | 37 ++ .../target/arm/as3525/sansa-m200v2/button-m200v2.c | 43 +++ .../target/arm/as3525/sansa-m200v2/button-target.h | 54 +++ .../target/arm/as3525/sansa-m200v2/system-target.h | 28 ++ .../target/arm/as3525/sansa-m200v2/timer-target.h | 38 ++ firmware/target/arm/lcd-ssd1815.c | 333 ++++++++++++++++++ firmware/target/arm/tcc77x/lcd-ssd1815.c | 256 -------------- 15 files changed, 1227 insertions(+), 256 deletions(-) create mode 100644 firmware/target/arm/as3525/sansa-e200v2/adc-target.h create mode 100644 firmware/target/arm/as3525/sansa-e200v2/backlight-target.h create mode 100644 firmware/target/arm/as3525/sansa-e200v2/button-e200v2.c create mode 100644 firmware/target/arm/as3525/sansa-e200v2/button-target.h create mode 100644 firmware/target/arm/as3525/sansa-e200v2/lcd-e200v2.c create mode 100644 firmware/target/arm/as3525/sansa-e200v2/system-target.h create mode 100644 firmware/target/arm/as3525/sansa-e200v2/timer-target.h create mode 100644 firmware/target/arm/as3525/sansa-m200v2/adc-target.h create mode 100644 firmware/target/arm/as3525/sansa-m200v2/backlight-target.h create mode 100644 firmware/target/arm/as3525/sansa-m200v2/button-m200v2.c create mode 100644 firmware/target/arm/as3525/sansa-m200v2/button-target.h create mode 100644 firmware/target/arm/as3525/sansa-m200v2/system-target.h create mode 100644 firmware/target/arm/as3525/sansa-m200v2/timer-target.h create mode 100644 firmware/target/arm/lcd-ssd1815.c delete mode 100644 firmware/target/arm/tcc77x/lcd-ssd1815.c (limited to 'firmware/target') diff --git a/firmware/target/arm/as3525/sansa-e200v2/adc-target.h b/firmware/target/arm/as3525/sansa-e200v2/adc-target.h new file mode 100644 index 0000000000..bea0272496 --- /dev/null +++ b/firmware/target/arm/as3525/sansa-e200v2/adc-target.h @@ -0,0 +1,24 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2008 ?? + * + * This program is free software;
