ADC10_A - Sample A11 (AVcc/2), Battery Monitor, LED OFF if AVcc < 2.3V

MSP430F550x Demo A single sample is made on A11 (AVcc/2) with reference to internal 1.5V Vref. Software sets ADC10SC to start sample and conversion - ADC10SC automatically cleared at EOC. ADC10_A internal oscillator times sample (16x) and conversion. ADC10BUSY flag is polled for EOC. If A11 (AVcc/2) < 0311h (1.15V) indicating AVcc is less 2.3V, P1.0 reset indicating a lo_Batt condition, else set. ACLK = n/a, MCLK = SMCLK = default DCO ~1.2MHz, ADC10CLK = ADC10OSC

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
• A11

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.

• None.
