I found an example of a random value generator but it says to be for x2xx boards. I still tried it but I got some errors that I don't know I can solve.
int TI_getRandomIntegerFromVLO(void)
{
unsigned int i;
int result = 0;
// setup Timer_A
TA0CCTL1 = CM_1 + CCIS_1 + CAP;
TA0CTL |= TASSEL__SMCLK + MC__CONTINOUS;
for(i=0 ; i<16 ; i++)
{
// shift left result
result <<= 1;
// wait until Capture flag is set
while(!(TA0CCTL1 & CCIFG));
// clear flag
TA0CCTL1 &= ~CCIFG;
// check LSB
if(TA0CCR1 & 0x01)
{
result |= 0x01;
}
// change the divison of timer input clock
TA0CTL = (TA0CTL & 0xFCFF) | ((TA0CCR1 & 0x03) << 8);
}
return result;
}

I am still not very familiar with the board, so I wanted to ask if this code is portable to my board, and if so, what should I change to get it working.
Apart from that, what is the idea of this generator ? It is supposed to be running from the beginning of the program and you ask for numbers whenever you need them ? If you start it when you ask for a number isn't it supposed to always return the same value ?
Thank you.
