CCS/BOOSTXL-SENSORS: add 14bit A/D data + red MSP432 board : how to use startWakeUpTimerA()

Part Number: BOOSTXL-SENSORS

Tool/software: Code Composer Studio

As I want to measure voltage with the accelerations, I add 14 bit ADC program as below 

(1) initialize ADC14

(2) start ADC14 conversion and get data and send it as text.

I can get the voltage with acceleration all right.  

input voltage 0.0 V

[Fri May 25 12:41:17.899 2018] accel,-832,440,16395,voltage,1

[Fri May 25 12:41:17.909 2018] accel,-830,442,16393,voltage,1

input voltage 1.3 V

3.3/2^14*6698 = 1.349 V

[Fri May 25 12:42:09.538 2018] accel,-834,450,16413,voltage,6698

[Fri May 25 12:42:09.548 2018] accel,-834,450,16413,voltage,6698

input voltage 3.1 V

3.3/2^14*15297 = 3.081 V

[Fri May 25 12:42:29.810 2018] accel,-830,439,16408,voltage,15297

[Fri May 25 12:42:29.820 2018] accel,-830,439,16408,voltage,15297

There is one problem.  

When I tried to wait for the completion of the ADC14 as below - 

            while(ADC14_isBusy())

            {

            }

The program is stopped here forever.  

So, I comment it out.  

Are there any better way to wait for completion of the ADC14 conversion ?

Just wait for several micro-second and read the result is OK ?

Hope to receive some answer soon !

            while(ADC14_isBusy())            {            }
