From 3520d8e90e7f6e3ffc88f8d1ff47fa3cc0efe960 Mon Sep 17 00:00:00 2001 From: Rafaël Carré Date: Wed, 17 Jun 2009 19:55:27 +0000 Subject: Sansa c200v2 : lcd & backlight support, using the c200v1 lcd driver The LCD driver is unified and lcd_send_command now takes 2 arguments : the command and its argument. If there is no argument, it's set to 0 and a NOP command is issued If there is more than one argument (set X/Y address), the 2nd argument is sent as a 2nd command, and a NOP command is issued after it. Benefit : c200v2 transfers the command and the argument in one 16 bits transfer Performance should not be affected since commands without argument are only used in lcd_init() and lcd_enable() lcd_send_data() now transfers whole lines (or columns) instead of single pixels yuv is disabled for c200v2 for now Some buttons can be read, including left button (bit 6 of DBOP_DIN), but for some reason they have no effect in rockbox: to be investigated git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21321 a1c6a512-1295-4272-9138-f99709370657 --- bootloader/sansa_as3525.c | 12 ++++-------- 1 file changed, 4 insertions(+), 8 deletions(-) (limited to 'bootloader/sansa_as3525.c') diff --git a/bootloader/sansa_as3525.c b/bootloader/sansa_as3525.c index 48f21bc196..7e6ac2dddb 100644 --- a/bootloader/sansa_as3525.c +++ b/bootloader/sansa_as3525.c @@ -27,7 +27,7 @@ #include #include "config.h" #include "lcd.h" -#include "backlight-target.h" +#include "backlight.h" #include "button-target.h" #include "common.h" #include "storage.h" @@ -48,14 +48,12 @@ void main(void) system_init(); kernel_init(); -#ifdef SANSA_C200V2 - /* stop here */ - while(1); -#endif + enable_irq(); + lcd_init(); show_logo(); - _backlight_on(); + backlight_init(); button_init_device(); int btn = button_read_device(); @@ -79,8 +77,6 @@ void main(void) verbose = true; } - enable_irq(); - ret = storage_init(); if(ret < 0) error(EATA,ret); -- cgit v1.2.3
