Ultimately, my goal with this chip is to sample some voltages and then relay that information to a computer (via the UART, which we now have running) and an LCD display. Now that the chip can talk to a computer we can start experimenting with the analog-to-digital converter.
For experimenting, I set up a voltage divider with a couple of resistors to be my sample voltage. I measured the voltage with a voltmeter at around 0.86 volts which should be suitable for sampling against either the internal 1.5V reference voltage or 2.5V reference voltage of the MSP430. Since I'll be using analog input A5 (or pin P1.5 of the microcontroller) as one
