Re: PIC32MZ Interleaved ADC configuration
I somehow suspect that, if there is not a button or an example in Harmony,
that you will have to do this the hard way.
The 12 bit SAR ADC in PIC32MZ__EF and PIC32MK are very similar.
There are also a number of Errata for the ADC modules, read the Errata document for the device you are using.
In addition to the Application Note you have found,
there is also the Family Reference Manual document: FRM Section 22, document DS60001344D or later revision.
It have more description, and example code for some modes of operation.
Even if the automatic interleaving, aka. Turbo mode, do not work,
it may be possible to use staggered triggering using 2 or 3 timers, and 2 or more Output Compare modules.
