ADC10B - Sample A1 Input, AVcc Ref, P1.0 and P3.5 is set if A1 > 0.5AVcc

MSP430FR573x Demo A single sample is made on A1 with reference to AVcc. 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 > 0.5*AVcc, P1.0 and and P3.5 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
• 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_VECTOR

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