From 0fac492c3da8b46ad1cf5a668e5d851c63443a94 Mon Sep 17 00:00:00 2001 From: Jens Arnold Date: Fri, 17 Aug 2007 06:45:18 +0000 Subject: First step of powermanagement rework: * Move target specific stuff into target tree, starting with battery voltage tables and voltage reading. (This revealed some incorrect percent_to_voltage_charging mappings). * Voltage reading on 1st gen ipods is now correct. * Clean up obsolete config #defines. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14375 a1c6a512-1295-4272-9138-f99709370657 --- firmware/target/arm/iriver/h10/powermgmt-h10.c | 71 ++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 firmware/target/arm/iriver/h10/powermgmt-h10.c (limited to 'firmware/target/arm/iriver/h10/powermgmt-h10.c') diff --git a/firmware/target/arm/iriver/h10/powermgmt-h10.c b/firmware/target/arm/iriver/h10/powermgmt-h10.c new file mode 100644 index 0000000000..18e3879c43 --- /dev/null +++ b/firmware/target/arm/iriver/h10/powermgmt-h10.c @@ -0,0 +1,71 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2002 by Heikki Hannikainen, Uwe Freese + * Revisions copyright (C) 2005 by Gerald Van Baren + * + * 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 "config.h" +#include "adc.h" +#include "powermgmt.h" + +const unsigned short battery_level_dangerous[BATTERY_TYPES_COUNT] = +{ +#ifdef IRIVER_H10 + 3760 +#elif defined IRIVER_H10_5GB + 3720 +#endif +}; + +const unsigned short battery_level_shutoff[BATTERY_TYPES_COUNT] = +{ +#ifdef IRIVER_H10 + 3650 +#elif defined IRIVER_H10_5GB + 3650 +#endif +}; + +/* voltages (millivolt) of 0%, 10%, ... 100% when charging disabled */ +const unsigned short percent_to_volt_discharge[BATTERY_TYPES_COUNT][11] = +{ +#ifdef IRIVER_H10 + { 3760, 3800, 3850, 3870, 3900, 3950, 4020, 4070, 4110, 4180, 4240 } +#elif defined IRIVER_H10_5GB + { 3720, 3740, 3800, 3820, 3840, 3880, 3940, 4020, 4060, 4150, 4240 } +#endif +}; + +/* voltages (millivolt) of 0%, 10%, ... 100% when charging enabled */ +const unsigned short percent_to_volt_charge[11] = +{ +#ifdef IRIVER_H10 + 3990, 4030, 4060, 4080, 4100, 4120, 4150, 4180, 4220, 4260, 4310 +#elif defined IRIVER_H10_5GB + /* TODO: Not yet calibrated */ + 3880, 3920, 3960, 4000, 4060, 4100, 4150, 4190, 4240, 4280, 4330 +#endif +}; + +#define BATTERY_SCALE_FACTOR 4800 +/* full-scale ADC readout (2^10) in millivolt */ + +/* Returns battery voltage from ADC [millivolts] */ +unsigned int battery_adc_voltage(void) +{ + return (adc_read(ADC_UNREG_POWER) * BATTERY_SCALE_FACTOR) >> 10; +} -- cgit v1.2.3
