Programming CC430F5137 using another microcontroller

If you want to take a stab at multiplexing or using shift registers, I would recommend visiting these links:

• The 74HC595 8 bit shift register
• Multiplexing using the CD74HC4067

The Arduino is used in both those tutorials, but it should be relatively easy to apply the same concepts to your microcontroller.

Set VCore() is a function that sets the core voltage regarding to the clock frequency. I am quite sure it looks for some feedback from the hardware to continue. Such as a bit that is set in a register when the voltage is stable. The simulator may not simulate this behavior and the program get stuck in an infinite loop, waiting on a flag that will never get the correct state. If you want to simulate this code, you can safely comment the vcore() line. It won't have any effect on the simulated result. Or, if you want to be cleaner, you could perform conditional compilation such as:

void main( void )
{  
    // Stop watchdog timer to prevent time out reset 
    WDTCTL = WDTPW + WDTHOLD; 

#ifdef SIMULATOR
    // Increase PMMCOREV level to 2 for proper radio operation
    SetVCore(2);
#endif                               

    ResetRadioCore();
    InitButtonLeds();
    InitTimer(); 
    ....

And then define SIMULATOR in you IDE when the code has to be simulated.

I am also sure that the program hangs on the initRadio for the same reason. It inits the RF part, but the simulator doesn't simulate it correctly and your code is waiting somewhere an answer that will never occur.
