Also, the included parts are:

MSP430G2231, 2KByte flash, 128b RAM, 10bit ADC
MSP430G2211, 2KByte flash, 128b RAM

The demo app consumes about 3/4 of the program memory. It sets up=20
timers, blinks an LED, waits for button press, measures temperature=20
(with on-die sensor), and then PWM modulates the onboard LEDs based on=20
temperature rise/fall.  I think it also reports something over the UART.

I wasted some time in the development environment trying to find the=20
simulator.  It turns out there is none - the in-circuit-debug facility=20
on the chip is pretty damn fantastic.  For example, you can hit "Halt",=20
change a clock control register, hit "Run" and the chip is now running=20
at a different speed...  It's interesting to scroll the disassembly=20
window and watch it fill in the as it reads the device memory to refresh=20
the listing. Recompiling the C project prompts to reload the chip and=20
then places you at the first line of main() with the chip halted, ready=20
for you to hit "run".  Seemed nice to me.
