George recommended this controller at the PyGTA meeting yesterday.

Free and Open Source Software (FOSS) tools (e.g. compilers and download
utilities) should probably get a little more emphasis from us when it
comes time to consider a sucessor to the 16F877.

Hello, All:

Following yesterday's discussion, here is more information on the
MSP430.

This chip is made by TI.  It has a 16-bit RISC core, and can run at
speeds up to 8 Mhz.  TI describes this chip as "mixed mode" (i.e. a
general purpose CPU with DSP features).  The MSP430 is extremely low
power.  Here is an overview from TI:

   "http://www.ti.com/msp430".

Open Source/Free Software tool availability is excellent, with a
fairly mature GCC port (MSPGCC):

   "http://mspgcc.sourceforge.net/".

I have used MSPGCC extensively, and have found the quality to be
excellent.  Optimization works well.  You can choose to optimize for
size instead of speed, which is frequently very important for
microcontroller applications.

The MSPGCC team actually makes excellent use of Python, for writing
the utilities which load the compiled binaries onto the target.

MSPGCC is easy to install under both Windows and Linux.  For Windows,
an installer is provided, and the package configures itself in a few
clicks.

Overall, this is a highly capable microcontroller with a complete
Free/Open Source toolchain -- definitely worth a look.

Best,

George.
