ADC12_A - Sample A0-3 Input, AVcc Ref, Repeated Sequence of Conversions

This example shows how to perform a repeated sequence of conversions using "repeat sequence-of-channels" mode. AVcc is used for the reference and repeated sequence of conversions is performed on Channels A0, A1, A2, and A3. Each conversion result is stored in ADC12MEM0, ADC12MEM1, ADC12MEM2, and ADC12MEM3 respectively. After each sequence, the 4 conversion results are moved to A0results[], A1results[], A2results[], and A3results[]. Test by applying voltages to channels A0 - A3. Open a watch window in debugger and view the results. Set Breakpoint1 in the index increment line to see the array values change sequentially and Breakpoint2 to see the entire array of conversion results in A0results[], A1results[], A2results[], and A3results[]for the specified Num_of_Results.

Note that a sequence has no restrictions on which channels are converted. For example, a valid sequence could be A0, A3, A2, A4, A2, A1, A0, and A7. See the MSP430x5xx User's Guide for instructions on using the ADC12_A.

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

ADC12_A peripheral
GPIO Port peripheral
A0
A1
A2
A3

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.
