2012-03-03Revise the PCM callback system after adding multichannel audio.Michael Sevakis
Additional status callback is added to pcm_play/rec_data instead of using a special function to set it. Status includes DMA error reporting to the status callback. Playback and recording callback become more alike except playback uses "const void **addr" (because the data should not be altered) and recording uses "void **addr". "const" is put in place throughout where appropriate. Most changes are fairly trivial. One that should be checked in particular because it isn't so much is telechips, if anyone cares to bother. PP5002 is not so trivial either but that tested as working.

2011-12-08AS3525v1/v2:Michael Sevakis
Fix problems with volume of recorded material by converting 14-bit samples to 16-bit. Remove duplicate samples from recorded data and support proper samplerate since ADC runs 1/2 the codec clock. Support monitoring mono on both output channels by feeding data manually to I2SOUT under the right conditions. DMA is no longer used for recording since frames must be processed as described above but it does allow full-duplex audio. Miscellaneous change includes a proper constant (HW_SAMPR_DEFAULT) to reset the hardware samplerate when recording is closed. PP5024 and AS3525 have different default recording rates (22kHz and 44kHz respectively) but both have half-speed ADC. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31180 a1c6a512-1295-4272-9138-f99709370657

2010-08-24Second try: Introduce plugin_crt0.c that every plugin links.Thomas Martitz
It handles exit() properly, calling the handler also when the plugin returns normally (also make exit() more standard compliant while at it). It also holds PLUGIN_HEADER, so that it doesn't need to be in each plugin anymore. To work better together with callbacks passed to rb->default_event_handler_ex() introduce exit_on_usb() which will call the exit handler before showing the usb screen and exit() after it. In most cases rb->default_event_handler_ex() was passed a callback which was manually called at all other return points. This can now be done via atexit(). In future plugin_crt0.c could also handle clearing bss, initializing iram and more. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27873 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

callback, zero data, alignment and stops are handled entirely inside pcm.c; driver merely calls fixed pcm.c callback. Remove pcm_record_more and do it just like playback; the original reason behind it isn't very practical in general. Everything checks out on supported targets. There wer some compat changes I can't check out on many unsupoorted but if there's a problem it will be a minor oops. Plugins become incompatible due to recording tweak-- full update.

2010-05-20S#10387 - Rework pluginlib actionsThomas Martitz
It changes pluginlib actions to contain only a single and simple context (and other one for remote directional buttons), consisting of 7(9) buttons: up/down/left/right, select OR short select and long select, exit and cancel (plus 2 for scrollwheel targets). This ensures contexts don't clash with other contexts and simplifies them, at the expense of reduced versatility. However, the versatility made it largely unusable due to the great number of targets. This should allow for using pluginlib actions safely for the most simple plugins (e.g. almost all demos). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26202 a1c6a512-1295-4272-9138-f99709370657

2010-05-14pitch_detector: Use continuous recording, even if the algorithm is too slow ↵Michael Sevakis
for that and record a whole buffer even if the min frequency is higher. Use the minimum samplerate that allows C-4186 to be detected (usually 11.025kHz, which can reduce computational load to 1/16 compared to 44.1kHz). Get rid of 64-bit multiplies when calculating input RMS value. Stop audio playback when entering plugin. Better backlight and CPU frequency handling. audio_sample_type->int16_t. simpler buffer size rounding. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26005 a1c6a512-1295-4272-9138-f99709370657
