It is impossible to have to have multiple functions running continuously on a
single core. They will need to share the core, to make this process simpler you
could use an RTOS.
However if your talking about keeping the ADC running alongside you code then
you do not need the RTOS, because the you can give the ADC a start and than
continue with your normal operation. The ADC can than give an interrupt when
ready. Using this you will reduce the time that you wait needlessly.
