Andrew Mahone af5bad46d8 Libfaad pow2/log2 improvements: 
Correct pow2_* to calculate correct output for input < 0.0 or between 0.0 and 1.0 instead of returning 0. This will change output, but the float version of this codec uses pow(2.0,x) in place of these functions, so this behavior was probably a bug
Replace 64-bit multiply in pow2_* with left or right shift by whole part of input, rounding if shifting right. An ARM-specific optimized version is provided as a C inline function, other targets use a C macro.
Increase constant size of table for pow2 to improve accuracy, also avoid early truncation in linear interpolation of result.
Move constant tables for pow2 and log2 to iram.

flash Simplify powermgmt thread loops so it calls functions turn (no more power_thread_sleep). Do other target-friendly simplifications, generic battery switch handling and split sim-specific code. Whoever can, please verify charging on the Archos Recorder (due to change in the charger duty cycle code). 2008-12-24 16:58:41 +00:00

wps Make the classic_statusbar.sbs more classic. Icons, position of numbers, charging animation (only tested on a colour display so far), volume as before but gets a 'clipping' icon on targets that allow more than 0dB, add channels indicator in the rec screen. The only difference on swcodec should be the disk activity indicator on flash targets (for now). On hwcodec there are small differences in the recording screen - quality display is simply using the system font (no wasting another bitmap on a slightly less taller Q), frequency uses icons now (keeping the differences between the sbs files smaller and with the small 'k' it's easier to understand, but debateable). Since the animation makes use of the viewport colour (shades) parameters, a classic_statusbar.grey.sbs was needed - reusing the colour one didn't work correctly anyways. The difference between Recorders (RTC) and Ondios (disk activity) is achieved through the 112x64x1.sbs file itself. 2009-11-28 16:37:33 +00:00

Build Your Own Rockbox

1. Check out 'rockbox' from SVN (or extract a downloaded archive).

   $ svn co svn://svn.rockbox.org/rockbox/trunk rockbox

     or

   $ tar xjf rockbox.tar.bz2

2. Create a build directory, preferably in the same directory as the firmware/
   and apps/ directories. This is where all generated files will be written.

   $ cd rockbox
   $ mkdir build
   $ cd build

3. Make sure you have sh/arm/m68k-elf-gcc and siblings in the PATH. Make sure
   that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
   a particular version depending on what player you are compiling for. These
   can be acquired with the rockboxdev.sh script in the /tools/ folder of the
   source, or will have been included if you've installed one of the
   toolchains or development environments provided at http://www.rockbox.org/

   $ which sh-elf-gcc
   $ which perl

4. In your build directory, run the 'tools/configure' script and enter what
   target you want to build for and if you want a debug version or not (and a
   few more questions). It'll prompt you. The debug version is for making a
   gdb version out of it. It is only useful if you run gdb towards your target
   Archos.

   $ ../tools/configure

5. *ploink*. Now you have got a Makefile generated for you.

6. Run 'make' and soon the necessary pieces from the firmware and the apps
   directories have been compiled, linked and scrambled for you.

   $ make
   $ make zip

7. unzip the rockbox.zip on your music player, reboot it and
   *smile*.

If you want to build for more than one target, just create several build
directories and create a setup for each target:

   $ mkdir build-fmrecorder
   $ cd build-fmrecorder
   $ ../tools/configure

   $ mkdir build-player
   $ cd build-player
   $ ../tools/configure
