ADC10_A - Sample A1-0 Inputs directly to DMA, AVcc Ref, Repeat Seq.

MSP430F550x Demo Use DMA to sample A1/A0 repeat sequence 32x(64 total samples) with reference to AVcc. Software sets ADC10SC to trigger sample burst. In Mainloop MSP430 waits in LPM0 to save power until ADC10_A conversion complete, DMA_ISR will force exit from LPM0 in Mainloop. ADC10_A internal oscillator times sample period (16x) and conversion (13x). DMA transfers conversion code to ADC_Result.

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
• DMA peripheral
• GPIO Port peripheral
• A1
• A0

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.

• DMA_VECTOR
