The Texas Instruments MSP430 microcontroller
The notes presented here are based around the Texas Instruments MSP430F149
microcontroller. Specifically, the notes were developed using the EasyWeb 2
board from Olimex. No responsibility is accepted for the suitability of these
code examples for any task.
Further information from Frank
The EasyWeb board can be bought here
I also have some notes for Olimex's EP9302 board here.

Some material relating to Olimex's H149 board.
Olimex sell a cheaper board called the MSP430-H149. It consists of the processor, a 32kHz watch crystal
and a PCB which brings the processor pins out to more robust headers.
I've found the whole clock business on the msp430 a bit confusing.
This little file program allows
you to route the various clocks to port pins so you can actually measure what is happening.
It may make a good starting point for someone trying to undestand the clocks.
This program includes serial I/O routines modified for the H149's
32kHz crystal. It allows the user increase and decrease the duty on pin 15 using a dumb terminal application
such as hyperterminal over an RS232 line.
Note:The H149's UART needs to be passed through a suitable line driver to make the logic levels compatible with RS232.
The Texas instruments compiler for the MSP430 can be found here
A simple 16 bit C-compiler to test out the examples above on a PC can be found here (Borland's Turbo C version 2.01)
