ADC10_A - Sample A2-0 Inputs directly to DMA, 8-Bit Res, Single Seq.

MSP430F550x Demo Sample A2/A1/A0 as single sequence with reference to AVcc. Software sets ADC10SC to trigger sample sequence. In Mainloop MSP430 waits in LPM0 to save power until ADC10_A conversion complete, DMA_ISR will force exit from any LPMx. ADC10_A internal oscillator times sample period (16x) and conversion (13x). DMA transfers conv results ADC_Result variable. Notice that the conversions go in the order of A2, A1, then A0.

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
• A2
• 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
