The code looks correct. It's possible that the adcResult array is not correctly defined, or read.

I don't think that problem is with the array.For example uint16_t val=(ADC12MEM0 & 0x0fff); does not work either. I tried MSP430F552x Demo - ADC12, Repeated Single Channel Conversions demo code it...

Forum Post: RE: MSP430FR5889 Timer and eUSCI Interrupt Problem (with Driverlib)

With the while loop, all you are doing is to wait in the loop as long as TxIFG is '0'. ie you are waiting until the TxIFG is set, before you wake-up the device and transmit the data. Without the while...
