ADC - Sample A7 Input, AVcc Ref, LED1 and LED2 is set if A7 > 0.5AVcc

MSP430FR4133 Demo A single sample is made on A7 with reference to AVcc. Software sets ADC10SC to start sample and conversion - ADC10SC 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, ADC10_ISR will force exit from LPM0 in Mainloop on reti. If A7 > 0.5*AVcc, LED1 and LED2 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:

• ADC10 peripheral
• GPIO Port peripheral
• A7

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.

• ADC10_VECTOR
