DMA is a basic tenet of Computer Architecture, review standard texts if required.

It is like a hardware memcpy(), paced by the peripheral.The samples appear inADCTripleConvertedValues[0] ADC1, Channel 1ADCTripleConvertedValues[1] ADC2, Channel 1ADCTripleConvertedValues[2] ADC3, Channel 1ADCTripleConvertedValues[3] ADC1, Channel 2...ADCTripleConvertedValues[0 + (SAMPLES / 2)]ADCTripleConvertedValues[1 + (SAMPLES / 2)]ADCTripleConvertedValues[2 + (SAMPLES / 2)]...For the respective HALF of the buffer, as filled at HT (Half Transfer) and TC (Transfer Complete)

You should use the other example, you clearly don't understand the Triple mode version you hacked up here.

You have to think about how it functions as a whole, not change a handful of parameters and ignore the relationships.
