Lambert, Niek 37c10e28b9 add patches form Niek Lambert 
* Added fixpointer version of altitude calculation.
when the two remaining filters get fixpointer replacments, a LOT of space gets free by not using floatpointer anywhere.
the fixpointer versions are also smaller in size.
* better display of weekday
* show time also in second line
* force gcc to not optimize anything in delay intrinsic

thanks a lot

README 

== Status ==

Works, but in development :-)

== Requirements ==

msp430-gcc4 http://mspgcc4.sourceforge.net/
make
python http://python.org

== Supported Compilers ==

msp430-gcc4
   Working combinations:
   gcc=4.4.3 binutils=2.20.1 libc=20100430

IAR msp430

Patches for more (more efficient) compilers are welcome :-)


== HOWTO ==

Copy gcc/intrinsics.h into [msp430-gcc-path]/msp430/include/intrinsics.h

To configure your image, run:

   make config

which will generate a config.h file that contains the settings for your build.

To compile the image run:

   make


It is HIGHLY suggested to make a clean build before you flash the image with:

   make clean main

== Problems ==

 * Compile / Link problems:
   If you get error messages like this one:

     msp430/bin/ld: build/eZChronos.elf section `.text' will not fit in region `text'
     .../msp430/bin/ld: section .vectors loaded at [000000000000ff80,000000000000ffff] overlaps section .text loaded at [0000000000008000,0000000000013343]
     .../msp430/bin/ld: region `text' overflowed by 13250 bytes
     collect2: ld returned 1 exit status

    or
     
     section .vectors loaded at [0000ff80,0000ffff] overlaps section .data loaded at [0000ff4e,0000ffcb]

   Your image is simply to large and will not fit into the flash. Try to disable some modules with make config and try again
   Or even better, send some patches that reduce code size ;-)

== Difference to the TI Firmware ==

 * More Features that can be configured with make config
 * Day of week
 * Disable 12h support (saves space)
 * Sleep Phase Clock - primary designed for http://github.com/poelzi/uberclock
 * The wireless flashing starts differently:
   Select RFBSL, Press DOWN to unlock, Press # long to start
 * No BlueRobin support. BlueRobin is a closed source binary blob.
   We don't have a compatible object file for that
 * Pressing STAR and UP long sets silent mode (no beep)

== Usefull Tools ==
 * mspdebug - debugger, proxy for gdb, flasher, ...  
     http://mspdebug.sourceforge.net
 * msp430static - static analyzer for sourcecode
     http://msp430static.sourceforge.net/
   run 'make source_index' to index all source files
