From c92bead2cfefaff61008f358ab223cf7b77bdc29 Mon Sep 17 00:00:00 2001 From: Robert Hak Date: Tue, 23 Apr 2002 08:50:38 +0000 Subject: a simple battery function to display a battery of passed width, length, and location on the player. As similar to the player display as I could get. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@186 a1c6a512-1295-4272-9138-f99709370657 --- uisimulator/battery.c | 102 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 102 insertions(+) create mode 100644 uisimulator/battery.c diff --git a/uisimulator/battery.c b/uisimulator/battery.c new file mode 100644 index 0000000000..1af8e71787 --- /dev/null +++ b/uisimulator/battery.c @@ -0,0 +1,102 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 1999 Robert Hak (rhak@ramapo.edu) + * + * Heavily modified for embedded use by Björn Stenberg (bjorn@haxx.se) + * + * All files in this archive are subject to the GNU General Public License. + * See the file COPYING in the source tree root for full license agreement. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ****************************************************************************/ + +#include "types.h" +#include "lcd.h" +#include "debug.h" +#define HAVE_RECORDER_KEYPAD +#include "button.h" + +#ifdef SIMULATOR +#include +#include +#endif + +/* I hacked this function to be placed inside because I figure we will need + something like it eventually. + + Args are fairly straight forward. + int xbase: location of "bottom" of battery on screen + int ybase: location of "left" edge of battery on screen + int len: how long is the battery to be (in pixels) + int wid: how tall is the battery to be (in pixels) + int percent: what percentage of the charge has been used + + Note: I am making use of the Logf() function until logging is + straightened out. +*/ + +void draw_battery(int xbase, int ybase, int len, int wid, int percent) +{ + float capacity = 0; + int bar_xoffset = 2; + int bar_yoffset = 2; + int bar_len = 0; + int bar_wid = wid - (bar_xoffset*2); + int i = 0; + + /* We only worry about length and width because if you place + the battery off the screen, its your own damn fault.
