ADC - Sample A7 input, 1.5V Shared Ref, LED ON if A7 > 0.5V

MSP430FR4133 Demo A single sample is made on A7 with reference to internal 1.5V Vref.Software sets ADCSC to start sample and conversion - ADCSC automatically cleared at EOC. ADC internal oscillator times sample (16x) and conversion. In Mainloop MSP430 waits in LPM0 to save power until ADC conversion complete, ADC_ISR will force exit from LPM0 in Mainloop on reti. If A7 > 0.5V, 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:

ADC peripheral
REF peripheral
Timer_A/Timer_B peripheral
GPIO Port peripheral

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.

ADC_VECTOR
TIMER0_A0_VECTOR/TIMER0_B0_VECTOR
