Daniel Poelzleithner fd3ff268c8 large update to sleep clock code and simplicti * implemented a nice send and receive framework. Code in simplic_tx_only loop can request receive window. In this window the recv of rf will be active and a R2R (ready to receive) package is sent. By then the AP should have filled outgoing buffer and a received handler is called. * made the sleep clock use initialisation. When starting the sleep clock, a new session id is requested that is sent with every package (3 bits), together with the couter (5 bits). When initialized a hash of the hardware address is sent so the clock can detect which watch is running. Also a currently unused program id can be sent to select the watch program later on.		13 years ago

README

== Status ==

Works, but in development :-)

== Requirements ==

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

== Supported Compilers ==

msp430-gcc4
IAR msp430

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


== HOWTO ==

Copy intrinsic.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 befor 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

   Your image is simply to large and will not fit into the flash. Try to disable some code with make config and try again :-)


== 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
