2013-04-27Provide high resolution volume and prescaler to hosted targets.Michael Sevakis
HAVE_SW_VOLUME_CONTROL is required and at this time only affects the SDL targets using pcm-sdl.c. Enables balance control in SDL targets, unless mono volume is in use. Compiles software volume control as unbuffered when PCM_SW_VOLUME_UNBUFFERED is defined. This avoids the overhead and extra latency introduced by the double buffer when it is not needed. Use this config when the target's PCM driver is buffered and sufficient latency exists to perform safely the volume scaling. Simulated targets that are double-buffered when made as native targets remain so in the sim in order to run the same code.

2013-04-22Do some cleanup, adjustment and a couple fixes to recent sound changes.Michael Sevakis
* SOUND_x enum can be generated by audiohw_settings.h along with settings entries and sound_val2phys. * VOLUME_MIN and VOLUME_MAX are no longer necessary within sound.c. If you need them, they are for target-defined purposes. * Fix up SDL volume implementation in sdl.c. Move sim volume calculation code to pcm-sdl.c. * Min trigger tresholds were based upon VOLUME_MIN for some reason. These setting have nothing to do with playback volume. Since it is no longer present, set these at -89dB which is the minimum peak meter sensitivity setting. * Fix an oversight in wm8758.c. I forgot to add the dB->register conversion to audiohw_set_volume. Change-Id: Ie1df33f1793eee75e6793f16bc7bddd16edb7f75

2013-04-15Straighten out the mad twisted state of sound.c and related areas.Michael Sevakis
This is going right in since it's long overdue. If anything is goofed, drop me a line or just tweak it yourself if you know what's wrong. :-) Make HW/SW codec interface more uniform when emulating HW functionality on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to- DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX" APIs are all in sound.c with none in DSP code any longer. Reduce number of settings definitions needed by each codec by providing defaults for common ones like balance, channels and SW tone controls. Remove need for separate SIM code and tables and add virtual codec header for hosted targets. Change-Id: I3f23702bca054fc9bda40f49824ce681bb7f777b
2013-04-11Fix f5a5b94 errors. Employ SW volume for select targets on SIM.Michael Sevakis
Onda VX747 sim was missing a limits #define; #include limits.h in pcm_sw_volume.h. Simply use the software volume control for the SIM volume control rather than the SDL volume control when the target would have it natively. Change-Id: I8e924a2ff1b410f602452d2ea9b691efb82c931e
2012-01-03Rework powermgmt to enable code re-use on appliation and sims.Thomas Martitz
* Introduce CONFIG_BATTERY_MEASURE define, to allow targets (application) to break powermgmt.c's assumption about the ability to read battery voltage. There's now additionally percentage (android) and remaining time measure (maemo). No measure at all also works (sdl app). If voltage can't be measured, then battery_level() is king and it'll be used for power_history and runtime estimation. * Implement target's API in the simulator, i.e. _battery_voltage(), so it doesn't need to implement it's own powermgmt.c and other stubs. Now the sim behaves much more like a native target, although it still changes the simulated battery voltage quickly, * Other changes include include renaming battery_adc_voltage() to _battery_voltage(), for consistency with the new target functions and making some of the apps code aware that voltage and runtime estimation is not always available. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31548 a1c6a512-1295-4272-9138-f99709370657

2011-02-08Initial maemo platform supportThomas Jarosch
Adds Nokia N900, N810 and N800 support. Features: - Introduce maemo specific platform defines - Play audio in silent mode - Stop playback on incoming calls - Battery level readout - Bluetooth headset support - Save CPU by disabling screen updates if the display is off or the app doesn't have input focus - N900: GStreamer audio backend Kudos to kugel for the code review. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29248 a1c6a512-1295-4272-9138-f99709370657

2010-06-26e200v1/c200v1: Implement limited samplerate switching. Rates 24kHz and below ↵Michael Sevakis
are being a bear as far as minor crackling at higher amplitude-- leave them out for the time being since no solution is currently evident. 48, 44, 32 (rec rates 24, 22, 16) seem perfectly fine. I'm betting c200 is ok to include because it uses the same setup as e200. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27139 a1c6a512-1295-4272-9138-f99709370657
2010-05-15- Move uisimulator/sdl/*.[ch] into the target tree, under ↵Thomas Martitz
firmware/target/hosted/sdl, uisdl.c is split up across button-sdl.c and system-sdl.c. - Refactor the program startup. main() is now in main.c like on target, and the implicit application thread will now act as our main thread (previously a separate one was created for this in thread initialization). This is part of Rockbox as an application and is the first step to make an application port from the uisimulator. In a further step the sim bits from the sdl build will be separated out. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26065 a1c6a512-1295-4272-9138-f99709370657
