ADC10B - Sample A1 input, 1.5V Shared Ref, LED ON if A1 > 0.5V

MSP430FR573x Demo A single sample is made on A1 with reference to internal 1.5V Vref.Software sets ADC10SC to start sample and conversion - ADC10SC automatically cleared at EOC. ADC10B internal oscillator times sample (16x) and conversion. In Mainloop MSP430 waits in LPM0 to save power until ADC10B conversion complete, ADC10_ISR will force exit from LPM0 in Mainloop on reti. If A1 > 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:

• ADC10 peripheral
• REF peripheral
• Timer_A 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.

• ADC10_VECTOR

• TIMER0_A0_VECTOR

  Built with IAR Embedded Workbench Version: 5.40 & Code Composer Studio V5.1
