reading voltage using TI's MSP430 FF22x4
This is the code that worked:

ADC10CTL1 = INCH_1 + CONSEQ_0;
ADC10CTL0 = SREF_1 + ADC10SHT_2 + REFON + ADC10ON + ADC10IE;
for (countDown = 240; countDown &gt; 0; countDown--); //delay to allow references to settle
ADC10AE0 |= 0x02;
ADC10CTL0 |= ENC + ADC10SC; //Sampling and conversion start
__bis_SR_register(CPUOFF + GIE);        // LPM0 with interrupts enabled
result = ADC10MEM; //result is a int
incomingVoltage[0] = result&amp;0xFF; //incoming voltage is an array of uint8_t, send it to AP
incomingVoltage[1] = (result&gt;&gt;8)&amp;0xFF; //this and previous line is similar to temperature sensing code sample


Thanks for the help!
