SUPPORTED SERIES: - NWZ-E450 - NWZ-E460 - NWZ-E470 - NWZ-E580 - NWZ-A10 NOTES: - bootloader makefile convert an extra font to be installed alongside the bootloader since sysfont is way too small - the toolsicon bitmap comes from the Oxygen iconset - touchscreen driver is untested TODO: - implement audio routing driver (pcm is handled by pcm-alsa) - fix playback: it crashes on illegal instruction in DEBUG builds - find out why the browser starts at / instead of /contents - implement radio support - implement return to OF for usb handling - calibrate battery curve (NB: of can report a battery level on a 0-5 scale but probabl don't want to use that ?) - implement simulator build (we need a nice image of the player) - figure out if we can detect jack removal POTENTIAL TODOS: - try to build a usb serial gadget and gdbserver Change-Id: Ic77d71e0651355d47cc4e423a40fb64a60c69a80
2014-01-26fonts: Fix regression(s) caused by c23ce62.Thomas Martitz
The builtin sysfont does not have an associated buflib_alloc_data (because it's builtin right?). font_get_{width,bits} accessed a field of it for all fonts which crashed on some systems but not on mine. Solution: Move this field to struct font directly. The cache size calculated was also busted. Fixes FS#12944 and most likely FS#12938. Change-Id: I32303c4335a12a6c421fdca34f7ece851aac12ca

2014-01-15fonts: Do not unload completely on USB.Thomas Martitz
The font engine can now perform cache lookups even if the font file is closed, if the font was disabled with the new font_disable_all() function. It is highly probable that the lookup succeeds but in the cache-miss case a blank, full-width glyph will be returned. Change-Id: I3c97e747d2a0ba30c7b495c6118c9f029d265b56
2014-01-05Do not include kernel.h in system.h.Thomas Martitz
system.h doesn't need it on its own and this change makes it less dependant on Rockbox internals. Change-Id: I4e1e4108a52a7b599627a829204eb82b392fc6d6

2012-05-02Use buflib for the allocation of voice PCM resources.Michael Sevakis
Buffers are not allocated and thread is not created until the first call where voice is required. Adds a different callback (sync_callback) to buflib so that other sorts of synchonization are possible, such as briefly locking-out the PCM callback for a buffer move. It's sort of a messy addition but it is needed so voice decoding won't have to be stopped when its buffer is moved. Change-Id: I4d4d8c35eed5dd15fb7ee7df9323af3d036e92b3

2011-03-05Anti-Aliased Fonts support.Thomas Martitz
This enables Rockbox to render anti-aliased fonts using an alpha blending method. The input font bitmaps are 4bit, i.e. 4x larger, but the metadata size stays the same. A tool, convttf, for converting ttf fonts directly to the Rockbox fnt format is provided. It has a useful help output, but the parameter that works best is -c1 or -c2 (2 for larger font sizes).

2010-08-01Rockbox as an application: add get_user_file_path().Thomas Martitz
For RaaA it evaluates user paths at runtime. For everything but codecs/plugins it will give the path under $HOME/.config/rockbox.org if write access is needed or if the file/folder in question exists there (otherwise it gives /usr/local/share/rockbox). This allows for installing themes under $HOME as well as having config.cfg and other important files there while installing the application (and default themes) under /usr/local. On the DAPs it's a no-op, returing /.rockbox directly. Not converted to use get_user_file_path() are plugins themselves, because RaaA doesn't build plugins yet. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27656 a1c6a512-1295-4272-9138-f99709370657
