ADC10_A - Sample A0 Input, AVcc Ref, LED ON if A0 > 0.5AVcc

MSP430F550x Demo A single sample is made on A0 with reference to AVcc. Software sets ADC10SC to start sample and conversion - ADC10SC automatically cleared at EOC.ADC10_A internal oscillator times sample (16x) and conversion. In Mainloop MSP430 waits in LPM0 to save power until ADC10_A conversion complete, ADC10_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:

  • ADC10_A peripheral
  • GPIO Port peripheral
  • A1

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_A_VECTOR
