ADC12_A - Sample A0 Input, AVcc Ref, LED ON if A0 > 0.5*AVcc MSP430F552x Demo

Description: A single sample is made on A0 with reference to AVcc. Software sets ADC12SC to start sample and conversion - ADC12SC automatically cleared at EOC. ADC12_A internal oscillator times sample (16x) and conversion. In Mainloop MSP430 waits in LPM0 to save power until ADC12_A conversion complete, ADC12_A_ISR will force exit from LPM0 in Mainloop on reti. If A0 > 0.5*AVcc, P1.0 set, else reset.

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

ADC12_A peripheral
GPIO Port peripheral
A0

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.
