The library is, but not the setup.

To run, the chip needs a clock. The example was made for the MSP430F2618, which can run at 16Mhz. The 2231 which you have can, but its not recommended. Since the MSP430 chips have an internal oscillator, they are factory calibrated to give precise selected frequencies. These calibration constants are stored on the chip when they are made.


The 2231 has only:




whereas the 2618 can goto 16Mhz




Now since you selected F2231, CALBC1_16MHZ is not defined, since it does not support it. You are stuck at 1Mhz. You can go to higher frequencies, but it will not be a calibrated frequency.
